Command-line switches for Microsoft Office products

When you launch a Microsoft Office product, the startup process runs in a standard way. Microsoft Word, for example, displays the Word splash screen and loads the Normal template. But suppose you want Word to start without its splash screen and then load a template other than the Normal template. Or, you want to customize the process even more by loading an add-in or running a macro upon startup. You can add options like this by using subcommands called command-line switches to an Office app's startup command.

If you want to use the customization just one time, you can type the command and switch in the Run dialog box (Start menu) in Microsoft Windows. If you want to use a particular switch many times or every time that you start the app, you can create a desktop shortcut that starts the program by using the same switch and parameters. This article describes how to do both. It also includes a table that lists all of the switches and parameters that are available in the desktop Office apps.

About commands, switches, and parameters

Using a command-line switch doesn't mean you have to type the whole startup command at the command prompt. You can start the Office app as usual, by clicking the program icon on the desktop, or by clicking the program name on the Start menu. All startup methods essentially do the same thing: they run the app's .exe file, even if you don't actually type the command or even see it.

A command-line switch is a modifier that is added to the .exe file. A startup file with a switch looks like this.

 outlook.exe /nopreview

In this example, a command-line switch has been added to the .exe file for Microsoft Outlook. The switch consists of a forward slash and a word or abbreviation that indicates the switch's action. This switch tells Outlook to launch without showing the Reading Pane.

A switch is sometimes followed by one or more specific instructions called parameters, which give the program further information about how to run the .exe command. For example, the following command tells Outlook to load a specific profile name upon startup.

outlook exe /profile profilename

Switch names cannot be abbreviated and are not case-sensitive. However, their parameters are sometimes case-sensitive.

Startup command names and locations

Here are the names of the startup commands for the Office products Word, Excel, PowerPoint, PowerPoint viewer, Outlook, and Access.

Word	winword.exe
Excel	excel.exe
PowerPoint	powerpnt.exe
PowerPoint Viewer	pptview.exe
Outlook	outlook.exe
Access	msaccess.exe

When you use one of the Office startup commands, you must supply the full path to the product's .exe file. Verify the location of this file on your computer. This table shows the locations of the .exe files if you accepted the default folder locations during installation.

In Office 2007	Windows 32-bit: C:\Program Files\Microsoft Office\Office12\ Windows 64-bit: C:\Program Files (x86)\Microsoft Office\Office12\
In Office 2010	Windows 32-bit: C:\Program Files\Microsoft Office\Office14\ Windows 64-bit: C:\Program Files (x86)\Microsoft Office\Office14\
In Office 2013	Windows 32-bit: C:\Program Files\Microsoft Office\Office15\ Windows 64-bit: C:\Program Files (x86)\Microsoft Office\Office15\
In Office 2016	Windows 32-bit: C:\Program Files\Microsoft Office\Office16\ Windows 64-bit: C:\Program Files (x86)\Microsoft Office\Office16\

Use a switch once by adding it to the Run command

1. In Windows 10, click the Search or Cortana icon in the taskbar, type Run, and then click Command Prompt in the results.

   In Windows 8, press the Windows key, type Run, and then press Enter.

   In Windows 7, click Start, point to All Programs, click Accessories, and then click Run.

2. In the Run dialog box, type a quotation mark, enter the full path for the app's .exe file, and then type another quotation mark. Alternatively, click Browse to locate and select the file. In this case, the quotation marks are supplied automatically.

3. After the closing quotation mark, type a space, and then type the switch. For example, you might type:

   "c:\program files\microsoft office\office15\outlook.exe" /nopreview  

The next time you start the app, it opens as usual. To make your customized startup available for repeated uses, see the next section.

Note the following about using command-line switches:

• You can use only one switch at a time. Starting an Office app with multiple switches is not supported.

• If the parameter is a path to a location on your computer, or a file name with spaces in it, enclose it in double quotation marks—for example, /t "Monthly Report.dotx".

• Switches and parameters are not case-sensitive. For example, /RO functions the same as /ro.

• Include one blank space before each switch and one before each parameter.

Make a switch available for reuse by creating a shortcut

1. Right-click the Windows desktop, point to New, and then click Shortcut on the shortcut menu.

2. In the Create Shortcut Wizard, in the Type the location of the item box, type a double quotation mark ("), enter the full path for the app's .exe file (including the file name), and then type another double quotation mark. (Alternatively, click Browse to locate and select the file. In this case, the quotation marks are added automatically.)

3. Following the closing quotation mark, type a space, and then type the switch and any parameters. If the parameter is a path to a location on your computer, and the path contains a space, it also must be enclosed in quotation marks. For example:

   "c:\program files\microsoft office\office15\excel.exe" /r "c:\My Folder\book1.xlsx"  

4. Click Next.

5. In the Type a name for this shortcut box, type a name for the shortcut, and then click Finish.

   The wizard creates the shortcut and places it on the desktop.

Whenever you want to use the shortcut to start the app, double-click it.

To add the desktop shortcut to the Windows Start menu, right-click the shortcut, and then click Pin to Start menu on the shortcut menu.

List of command-line switches for Office products

Word Excel PowerPoint, PowerPoint Viewer Outlook Access



Switch and parameter	Description
/safe	Starts Word in Safe Mode.
/q	Starts Word without displaying the Word splash screen.
/ttemplatename	Starts Word with a new document based on a template other than the Normal template. Example    To start Word with a document based on a template called Myfax.dotx, stored on the C drive, type the following at the command prompt: /tc:\Myfax.dotx Note: Do not include a space between the switch and the name of the template file. Security Note: Because templates can store macro viruses, be careful about opening them or creating files based on new templates. Take the following precautions: run up-to-date antivirus software on your computer, set your macro security level to high, clear the Trust all installed add-ins and templates check box, use digital signatures, and maintain a list of trusted sources.
/t filename	Starts Word and opens an existing file. Example    To start Word and open the template file Myfax.dotx, stored on the C drive, type the following at the command prompt: /t c:\Myfax.dotx Example    To start Word and open multiple files, such as MyFile.docx and MyFile2.docx, each stored on the C drive, type the following at the command prompt: /t c:\MyFile.docx c:\MyFile2.docx
/f filename	Starts Word with a new document based on an existing file. Example    To start Word and create a new document based on file MyFile.docx, stored on the desktop, type the following at the command prompt: /f "c:\Documents and Settings\All Users\Desktop\MyFile.docx"
/h http://filename	Starts Word and opens a read-only copy of a document that is stored on a Microsoft Windows SharePoint Services site. The site must be on a computer that is running Word 2007 or later or Windows SharePoint Services 2.0 or later. Example    To start Word and open a copy of file MyFile.docx, stored in a document library at the URL http://MySite/Documents, type the following at the command prompt: /h http://MySite/Documents/MyFile.docx Note: If the document is checked out to you, the /h switch has no effect. Word opens the file so that you can edit it.
/pxslt	Starts Word and opens an existing XML document based on the specified Extensible Stylesheet Language Transformation (XSLT). Example    To start Word and apply the XSLT MyTransform, stored on the C drive, to the XML file Data.xml, also stored on the C drive, type the following at the command prompt: /pc:\MyTransform.xsl c:\Data.xml
/a	Starts Word and prevents add-ins and global templates (including the Normal template) from being loaded automatically. The /a switch also locks the setting files.
/ladd-in	Starts Word and then loads a specific Word add-in. Example    To start Word and then load the add-in Sales.dll, stored on the C drive, type the following at the command prompt: /lc:\Sales.dll Note: Do not include a space between the switch and the add-in name. Security Note: Use caution when running executable files or code in macros or applications. Executable files or code can be used to carry out actions that might compromise the security of your computer and data.
/m	Starts Word without running any AutoExec macros.
/mmacroname	Starts Word and then runs a specific macro. The /m switch also prevents Word from running any AutoExec macros. Example    To start Word and then run the macro Salelead, type the following at the command prompt: /mSalelead Note: Do not include a space between the switch and the macro name. Because macros can contain viruses, be careful about running them. Take the following precautions: run up-to-date antivirus software on your computer; set your macro security level to high; clear the Trust all installed add-ins and templates check box; use digital signatures; maintain a list of trusted publishers.
/n	Starts a new instance of Word with no document open. Documents opened in each instance of Word will not appear as choices in the Switch Windows list of other instances.
/w	Starts a new instance of Word with a blank document. Documents opened in each instance of Word will not appear as choices in the Switch Windows list of the other instances.
/r	Re-registers Word in the Windows registry. This switch starts Word, runs Office Setup, updates the Windows registry, and then closes.
/x	Starts Word from the operating system shell so that Word responds to only one Dynamic Data Exchange (DDE) request (for example, to print a document programmatically).
/ztemplatename	Visibly behaves exactly like the /t switch. However, you can use the /z switch with Word to generate both a Startup and a New event, whereas the /t switch generates only a Startup event.

Switch and parameter	Description
workbook path | file name This parameter does not require a switch.	Starts Excel and opens the specified file. Example excel.exe "c:\My Folder\book1.xlsx" or excel.exe http://MySite/Book1.xlsx
/r workbook path | file name	Opens a specific workbook as read-only. Example excel.exe /r "c:\My Folder\book1.xlsx" or excel.exe /r http://MySite/Book1.xlsx
/t workbook path | file name	Starts Excel and opens the specified file as a template. Example excel.exe /t "c:\My Folder\book_name.xlsx". or excel.exe /t http://MySite/book_name.xlsx
/n workbook path | file name	Like /t, starts Excel and opens the specified file as a template. Example excel.exe /n "c:\My Folder\book_name.xlsx". or excel.exe /n http://MySite/book_name.xlsx
/e or /embed	Prevents the Excel startup screen from appearing and a new blank workbook from opening. Example excel.exe /e
/p workbook path	Specifies a folder as the active working folder (for example, the folder that is pointed to in the Save As dialog box). Example excel.exe /p "c:\My Folder"
/s or /safemode	Forces Excel to bypass all files that are stored in startup directories, such as the default XLStart folder located in the directory where Excel or Microsoft Office is installed. Example excel.exe /s
/m	Creates a new workbook that contains a single XLM macro sheet. Example excel.exe /m
/a progID	Starts Excel and loads the Automation add-in that is specified by the progID of the add-in. Example excel.exe /a MyProgId.MyProgID2.1
/x	Starts a new instance (a separate process) of Excel. Example excel.exe /x "c:\My Folder\book1.xlsx" or excel.exe /x http://MySite/Book1.xlsx

Here are the command-line switches that are available for PowerPoint.

Switch or parameter	Action
/B	Starts PowerPoint with a new blank presentation. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /B
/C	Starts PowerPoint with the specified file open and also starts Microsoft Windows NetMeeting conferencing. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /C NetMeetingPresentation.pptx Note: If you use this switch without specifying a file, PowerPoint starts with no presentation open and NetMeeting conferencing is not started.
/EMBEDDING	Starts PowerPoint without displaying the Office PowerPoint 2007 program window. Developers use this switch when testing add-ins. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /EMBEDDING
/M MACRO	Runs a macro in a specified presentation. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /M myfile.pptm "MyMacro" "MyMacro" is a macro in the file myfile.pptm.
/N	Starts PowerPoint and creates a new presentation. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /N "Path\templatename.potx" This example specifies the name of the template that the new presentation is based on: templatename.potx. If a template name is not supplied, PowerPoint starts a new presentation based on the blank template (in effect, the same as using the /N switch without a template name).
/O	Starts PowerPoint and specifies a list of files to open. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /O File name1.pptx, File name2.pptx
/P	Prints the presentation to the default printer by using default settings. When you use the /P switch, PowerPoint displays the Print dialog box before printing. After you choose options and click OK, the dialog box closes, and PowerPoint prints the file and then closes. If you don't want to see PowerPoint at all, use the /PT (Print To) switch instead. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /P "MyFile.pptx"
/PT	Prints the presentation to the specified printer by using the default settings. If you don't want to see PowerPoint at all, use the /PT (Print To) switch. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /PT "PrinterName" "" "" "MyFile.pptx" PrinterName is the name of the printer that appears in the Name box under Printer in the Print dialog box. The empty quotation marks are necessary; the quotation marks around PrinterName and the path to the PPTX file are needed only if there are spaces in either of the names, but it is always a good idea to use them.
/PMO	Prints the specified file, but show the Print dialog box. When you use the /P switch, PowerPoint displays the Print dialog box before printing. After you choose options and click OK, the dialog box closes, and PowerPoint prints the file and then closes. If you don't want to see PowerPoint at all, use the /PT (Print To) switch instead. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /PMO "MyFile.pptx"
/RESTORE	Restores PowerPoint to the way it was before the program closed abnormally. When PowerPoint restarts, it will attempt to recover and restore some aspects of the state of the program and presentations before it closed. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /RESTORE
/S	Opens the specified presentation file as a slide show. Example: "c:\program files\microsoft office\office12\POWERPNT.exe" /S "Presentation1.pptx"

Here are the command-line switches that are available for PowerPoint Viewer.

Switch or parameter	Action
/D	Shows the Open dialog box when the presentation ends. Example: "c:\program files\microsoft office\office12\PPTVIEW.exe" /D
/L	Reads a playlist of PowerPoint presentations contained within a text file. Example: "c:\program files\microsoft office\office12\PPTVIEW.exe" /L "Your_Play_List.txt " Note: The playlist file is a list of presentation file names (preceded by the path as needed). It is not possible to add additional command-line switches to the individual presentations within the playlist.
/N#	Opens the presentation at a specified slide number, instead of slide 1. Example: "c:\program files\microsoft office\office12\PPTVIEW.exe" /N5 "Presentation.pptx" This example opens Presentation.pptx at slide 5.
/S	Starts the viewer without showing the splash screen. Example: "c:\program files\microsoft office\office12\PPTVIEW.exe" /S
/P	Sends the presentation to a printer, and print the file. Example: "c:\program files\microsoft office\office12\PPTVIEW.exe" /P "Presentation.pptx" This example prints the Presentation.pptx file.

Switch	Description
/a	Creates an item with the specified file as an attachment. Example: "c:\program files\microsoft office\office15\outlook.exe" /a "c:\my documents\labels.doc" If no item type is specified, IPM.Note is assumed. Cannot be used with message classes that are not based on Outlook.
/altvba otmfilename	Opens the VBA program specified in otmfilename, instead of %appdata%\microsoft\outlook\vbaproject.otm.
/c messageclass	Creates a new item of the specified message class (Outlook forms or any other valid MAPI form). Examples: /c ipm.activity creates a Journal entry /c ipm.appointment creates an appointment /c ipm.contact creates a contact /c ipm.note creates an e-mail message /c ipm.stickynote creates a note /c ipm.task creates a task
/checkclient	Prompts for the default manager of e-mail, news, and contacts.
/cleanautocompletecache	Removes all names and e-mail addresses from the Auto-Complete list. (Outlook 2013, 2016 only)
/cleancategories	Deletes any custom category names that you have created. Restores categories to the default names.
/cleanclientrules	Starts Outlook and deletes client-based rules.
/cleanconvongoingactions	Deletes the Conversations Actions Table (CAT). CAT entries for a conversation thread usually expire 30 days after no activity. The command-line switch clears all conversation tagging, ignore, and moving rules immediately stopping any additional actions. (Outlook 2013, 2016 only)
/cleandmrecords	Deletes the logging records saved when a manager or a delegate declines a meeting.
/cleanfinders	Resets all Search Folders in the Microsoft Exchange mailbox for only the first profile opened.
/cleanfromaddresses	Removes all manually added From entries from the profile.

/cleanrules	Starts Outlook and deletes client-based and server-based rules. Important If you have multiple or additional mailboxes in your Outlook profile, running the /cleanrules command line switch deletes the rules from all connected mailboxes. Therefore, it is recommended that you only run this command when your Outlook profile only contains the one, target mailbox.
/cleanserverrules	Starts Outlook and deletes server-based rules.
/cleansharing	Removes all RSS, Internet Calendar, and SharePoint subscriptions from Account Settings, but leaves all the previously downloaded content on your computer. This is useful if you cannot delete one of these subscriptions within Outlook 2013.
/cleansniff	Overrides the programmatic lockout that determines which of your computers (when you run Outlook at the same time) processes meeting items. The lockout process helps prevent duplicate reminder messages. This switch clears the lockout on the computer it is used. This enables Outlook to process meeting items.

/promptimportprf	Same as /importprf except a prompt appears and the user can cancel the import.
/recycle	Starts Outlook by using an existing Outlook window, if one exists. Used in combination with /explorer or /folder.
/remigratecategories	Starts Outlook and starts the following commands on the default mailbox: Upgrades colored For Follow Up flags to Outlook 2013 color categories. Upgrades calendar labels to Outlook 2013 color categories. Adds all categories used on non-mail items into the Master Category List Note: This is the same command as Upgrade to Color Categories in each Outlook mailbox properties dialog box.
/resetfolders	Restores missing folders at the default delivery location.
/resetfoldernames	Resets default folder names (such as Inbox or Sent Items) to default names in the current Office user interface language. For example, if you first connect to your mailbox in Outlook by using a Russian user interface, the Russian default folder names cannot be renamed.

Switch	Parameter	Description
None	database	Opens the specified database or Microsoft Access project. You can include a path, if necessary. If the path contains spaces, enclose it in quotation marks.
/excl	None	Opens the specified Access database for exclusive access. To open the database for shared use in a multiuser environment, omit this switch. Applies to Access databases only.
/ ro	None	Opens the specified Access database or Access project for read-only use.
/runtime	None	Specifies that Access will start with runtime version options.
/profile	user profile	Starts Access by using the options in the specified user profile instead of the standard Windows Registry settings created when you installed Access. This replaces the /ini switch used in versions of Access prior to Access 95 to specify an initialization file.
/compact	target database or target Access project	Compacts and repairs the Access database, or compacts the Access project that was specified before the /compact switch, and then closes Access. If you omit a target file name following the /compact switch, the file is compacted to the original name and folder. To compact to a different name, specify a target file. If you include a path that contains spaces, enclose the path in quotation marks. If you specify a file name in the target database or target Access project parameter but you don't include a path, the target file is created in the default database folder that is specified in Access. You can change this setting in the Access Options dialog box. In an Access project, this option compacts the Access project (.adp) file but not the Microsoft SQL Server database.
/x	macro	Opens the Access database that was specified before the /x switch, and then runs the specified macro. Another way to run a macro when you open a database is to create a macro named AutoExec. Macros can contain viruses, so you must be careful about running them. Take the following precautions: run up-to-date antivirus software on your computer; use the Trust Center to disable all macros except those that are digitally signed; maintain a list of trusted sources of macros.
/ cmd	None	Specifies that what follows on the command line is the value that will be returned by the Command function. This option must be the last switch on the command line. You can use a semicolon (;) as an alternative to /cmd. Use this switch to specify a command-line argument that can be used in Visual Basic for Applications (VBA) code.
