We recently received an email from the UMB email administrators concerning the iOS11 Mail app and Office365. If you are using the Mail app on your iPhone or iPad, and upgrade to iOS 11, you may encounter issues with your school email. How does this affect me? Due to an incompatibility in the new release of iOS, users of the built-in Apple Mail app in iOS 11 may be unable to sync their Office 365 mailbox or login to their accounts. iOS 9 or 10 users are not affected. What do I need to do to fix this? Microsoft and Apple are working to resolve this issue and will post more information to the article, below, when it becomes available. In the meantime, we recommend you download the free Outlook for iOS client, available in the App Store. Alternatively, you can avoid updating to iOS 11 until the issue has been fixed.

Or if you want to update to the new iOS 11, then it would be best to download the Outlook app, and set that up first, per campus instructions.
