Check your sign-in address

1. Check the format of your sign-in address. It should look something like KatieJ@contoso.com. Be sure to use your organization credentials, not your Skype Name or Microsoft account.

   Your sign-in address may be different from the format you use to sign in to your organization's network.

2. You may be asked for both a user ID and a sign-in address. For most organizations, these two are the same, so enter your user ID in both boxes.

Re-enter your password

If you recently changed your password, you might need to re-enter your new password in Skype for Business. Here's how:

Note: If you're signing in to Skype for Business for the first time, enter your Office 365 user ID, click Sign In, enter your password, and click Sign In again.

1. On the Skype for Business sign in screen, click Delete my sign-in info.

   Note: If you're stuck at "Contacting server and signing in," click Cancel Sign-In.

   

2. In the window that appears, click Yes.

3. Click Sign In.

   

4. Under Password, enter your password, and click Sign In.

   

Check if your password works with Office 365

Try using your sign-in address and password to sign in to Office 365:

1. In a browser, go to Office.com.

2. In the top right corner of the screen, click Sign in.

   

3. Enter the sign-in address and password you use to sign in to Skype for Business, and click Sign in.

If you can't sign in to Office 365, your password might be incorrect. Try resetting your password.

Reset your password

If you've forgotten your password or it's no longer working, use the Microsoft Online Password Reset site to send a new password request to your workplace technical support—typically the person who set up your Office 365 account for you.

Update your computer's date and time

If you're getting an error that your clock is wrong, try updating your computer's date and time. Follow the instructions for your version of Windows:

Windows 7

1. Go to a website that shows Coordinated Universal Time (UTC).

2. Go to Control Panel > Date and Time, and note the UTC offset for your location.

1. If you need to, choose Change date and time and update your computer's clock.

2. Try signing in again.

Windows 8 and Windows 10

1. Go to a website that shows Coordinated Universal Time (UTC).

2. Go to Setting > PC Settings > Time and Language.

3. Note your UTC offset, and compare your device's time to that shown on the website.

If you need to update your device's time:

1. Turn off Set time automatically and tap Change.

2. Update the time and tap Change.

3. Try signing in again.

How do I sign in to Skype for Business on Mac?

How do I reset my password?

What's the format of my sign-in address?
