    Hi @Lindylu Evridge ,

    Welcome to our forum!

    According to my research, the issue may be related to authentication, you can try to resolve the issue by doing the following:

    • On iPhone: go to settings, Mail, Accounts, Add Account
    • Choose to add a Microsoft Exchange account. Use Microsoft 365 email/password
    • Choose options you want to add (mail, calendar, etc.)
    • Add the account
    • Go to Outlook app and add new Microsoft 365 account
    • When switching to Authenticator, you should now be able to proceed instead of seeing the “something went wrong” message.
