    Hello thanks for the Info, but once you disable the remote mailbox shouldnt the enable script be “Enable-Remote ID -RemoteRoutingAddress“?

      Hi, After disabled the remote mailbox, I tried the Enable-RemoteMailbox and waited for a couple of sync but no luck. Therefore, created a mailbox (Enable-Mailbox) and migrated to cloud.

    Great Post. I had a similar issue and could not find an answer. Followed your steps forced a sync then re-enabled the account and the mailbox was back to a user mailbox and immediately accessable.

    Hmm the mailbox I tried this with was deleted and was not able to recover it. It never showed up in the disconnected mailboxes and when I enabled the mailbox it just started a fresh one. When I $dbs = Get-MailboxDatabase
    >> $dbs | foreach {Get-MailboxStatistics -Database $_.DistinguishedName} | Format-Table DisplayName,Database,DisconnectDate I see two mailboxes of the same name.
