we use Microsoft Exchange 2019 onPrem and Sophos AD Sync to sync all AD accounts, shared mailboxes and groups to Sophos.
Unfortunately, when I try to add a shared mailbox as a managed mailbox in Sophos Mail, I get the following error:
Email address and account do not match. (AS38)
Is there any way to add shared mailboxes to Sophos Mail? I couldn't find any instructions on how to do this in the Sophos documentation.
Thank you very much for your help.
