Have you experienced an inconsistency with some mailboxes going into a quarantined state after being migrated to Exchange Server 2019 that seemed unexplainable? I had this very situation.

Should the Exchange 2019 Metacache Database Actually Be Implemented?

At Ignite 2018, Microsoft outlined several details related to Exchange Server 2019 that I previously wrote about. Included was the new Metacache Database (MCDB).

Quick Tip: Attaching a Mailbox to a Different Active Directory User

Situation: Cross-forest migrations have a lot of moving parts. It requires two AD forests with accounts or trusts established, … Continue reading Quick Tip: Attaching a Mailbox to a Different Active Directory User

However, Active Directory [Domain Services] is a little more complicated than that and Exchange Server is the canary in the coal mine, so to speak.
