Long story short, all system mailbox accounts were deleted.
I recreated the typical system mailbox accounts with the setup.exe /PrepareAD.
Problem is, the system mailboxes that are unique to the Database are also gone and need recreated. These system accounts are NOT recreated when rerunning the setup etc.
All mail flow outbound to other databases or email accounts outside of the organization have stopped. All inbound email is still working.
How do I recreate these accounts?
The Microsoft Exchange Mailbox Replication service was unable to process jobs in a mailbox database.
Database: ******
Error: Couldn't find system mailbox '49420906-3123-4a3e-bf1e-b9f3f607801a' in Active Directory.
I have three databases missing their accounts.
Thank you in advance!
P.S. Side note. Bombarded with these errors. Not sure if its related.
A fatal alert was received from the remote endpoint. The TLS protocol defined fatal alert code is 46.
