Removing/re-adding staff email in Outlook for iOS post-migration

Once your staff mailbox has been migrated to Office 365, you will need to remove and re-add your email account in your Outlook app if you use an iOS device.

When you are advised that your email account migration is complete, do the following:

1. Launch Outlook and tap the top-left home icon to find your account.
   
   
2. Tap the Settings cog in the bottom left.
   
   
3. Tap your staff email (Exchange) account in the list under Mail Accounts.
   
   
4. Tap Delete Account at the bottom, then tap Delete From This Device to confirm deletion.
   
   
5. You have now deleted your account from Outlook and can re-add it by tapping Add Mail Account then selecting Add Email Account on the next screen.
   
   
6. Type in your staff email address and tap Sign In with Office 365.
   
   
7. If you are off-campus or using mobile data, you may now be prompted for MFA - for more information about this, see the related answer: Multi-factor authentication (MFA). Tap Open Authenticator and log in, or if using SMS, just log in.
   
   
8. You should now be prompted to Approve sign-in (either by receiving an SMS or using the Authenticator app). If this fails, you can tap the Sign in another way link and request the prompt again.
   
   
9. Your account has now been re-added to Outlook and can be used again. Your email and calendar may take a short time to re-sync and appear correctly within the app.
