   You may have named your profile something other than Exchange MIT, go into whichever account is your MIT Exchange account.
2. Next to "Account" confirm it lists your full email address, username@mit.edu.
3. If it does not list your full email address, click on the address to update it to list your full address in the form username@mit.edu

Android

On most Android phones you can't edit existing account email addresses. If your phone's email client doesn't automatically work after migration, you'll need to delete your MIT account and set it up again to use the native mail client. Alternatively you can install one of the native apps for Android: Outlook or Outlook.

• Go to Settings > Accounts & sync
• Select your MIT Exchange account and select ... > Remove
• Confirm that you want to remove your account.
• Click the + sign to add an account.
• Select Exchange Active Sync
• Enter your full MIT email address in the form username@mit.edu and your password. Click Next
• Choose your ActiveSync settings and click Next
• Enter your account name in the form username@mit.edu and click Finish Setup
  Result: Your email is configured.

Exact instructions can vary from brand to brand. For more help with Android configuration, see Microsoft's Set up email on an Android phone or tablet

Apple Mail/iCal

Apple Mail/iCal users cannot update their existing account information for M365 as Apple does not allow editing of the username field. You must wait until after migration, delete the existing Exchange account and create a new one. For instructions, see:

• Microsoft 365 - Email and Calendaring - Apple Mail and iCal Configuration

Outlook Web Access/Exchange on the Web

Instead of Outlook Web Access, you now get Exchange on the Web. There is a new URL for accessing your email and calendaring from this M365 web application after migration.
