We have Azure AD Sync with Office365 Hybrid Setup.
All mail enabled objects are moved into O365 cloud.
User Mailboxes, Shared Mailboxes and Distribution Groups are synced fine into Sophos Central via Azure Ad Sync.
Only Mail enabled Public Folders are missing. Is there something more to do or do we really have to import all email alias manually via CSV?
I had Sophos AD Sync before and onPremises PublicFolders where synced.
This is the same issue I have too. See my post below
Azure Directory Sync not detecting public folders - Discussions - Sophos Email - Sophos Community
According to sophos support it's a 365 thing not showing these public folders as mailboxes - personally I'm not so sure that's the case.
My biggest issue is the sophos platform isn't letting me edit or delete the old on prem sync'd public folders - the option is disabled and I'm stuck with them. Sophos didn't help with that either.
If the VIP protection wasn't so good to have I'd have removed the service again, not really what you want gold partners to do.
