Migrating shared mailboxes between hybrid environments on same Office 365 tenant
Hi there,
We have the following setup:
One Office 365 tenant shared by multiple on-premises Active Directories, all using Dirsync to sync accounts up to Office 365. All are hybrid setup a...
A quicker way, although not really supported one, would be to filter the shared mailbox out of the scope of the "A" DirSync. This will remove it in O365, but you can immediately recover it from the recycle bin, which will leave it as "disconnector". Meaning, you can now remove it's immutableID and match it against any other On-Prem object (including the ones from other ADs).
