    @techies Check if that mailbox is correctly set up. If it is, check if the mailbox is on-premises. If it is on-premises it may need to be migrated from Exchange to Microsoft 365

    If you know it's an Exchange mailbox you should migrate it or have your admin migrate it to Office 365.

    Check how to do it here:
