Exchange account server settings

If you are trying to set up an Exchange account in Outlook, ask the organization that gave you the email address for the name of your Exchange server. It's standard for them to provide you with this information so you can add your email address to a computer or phone.

If you are trying to set up an Office 365 for business account with Outlook, see POP and IMAP settings for Outlook Office 365 for business for the incoming (IMAP) and outgoing mail (SMTP) server names .

If you are using Outlook on a Mac, to access these settings from the primary Exchange Accounts preferences dialog box, in Outlook click File > the Advanced button, and then click the Server tab.

Option	Description
Microsoft Exchange Server	If Outlook cannot automatically detect your Exchange server, you can enter its address here. To find out the name of your Exchange server, you have to contact the person who gave you the email address, or contact someone in your IT department, for the name of your Exchange server.
Override default port	To be able to edit the port number that follows the server address, select this check box.
Use SSL to connect (recommended)	Secure Sockets Layer (SSL) is an encryption technology that helps improve the security of the account.
Download headers only	If you have a slow network connection, you can use this option to improve performance. Only message headers are automatically downloaded to your computer. Therefore, large messages (and any attachments) are downloaded only if you select them in the message list. However, when you are offline, you can't read the message bodies or attachments.
