    Hi,

    Your guidance was helpful and i identified that the renewed license was not linked to the user, and that the issued persisted as the user could not be linked to the renewed license. I finally found where to link the user and renewed license after which the profile, mail, etc. updated and sync'ed.

    UPN has been changed and the onmicrosoft did not cause the issue.

    Thanks - your support was appreciated.

    Please note that this is the da-dk forum. I kindly recommend posting your question in Danish so that more community members can assist you. Alternatively, you may consider posting in the English forum if you prefer to use your native language.

    Hi @Mette Viborg

    The error in the Outlook log shows:

    OwaUserHasNoMailboxAndNoLicenseAssignedException

    This indicates that Outlook was able to locate and authenticate the account, but it could not find an Exchange Online mailbox associated with the user, or the user does not currently have an Exchange Online license assigned. To resolve this, assign a valid license to the user.

    You mentioned that when signing in with @ANUIA.onmicrosoft.com, it shows the account does not exist. This could indicate that the User Principal Name (UPN) was changed previously from the .onmicrosoft.com address to the custom domain address.

    Could you please confirm whether the UPN for this admin account was changed at any point?

    As a test, please try signing in to the Microsoft 365 Admin Center using the @anuia.dk account at:

    Microsoft 365 Admin Center

    If you can successfully access the Admin Center, please also check the user's current sign-in name (UPN) and whether an Exchange Online license is assigned to the account.

    Please try and let me know how it goes.
