Hey everyone, I have a bit of a situation with our on-prem Exchange setup. We've got an AD user (DOMAINexample) whose account has somehow gotten corrupted, so we created a new AD user (DOMAINexamplenew). Now, I want to assign the existing mailbox from the old user to the new one so they can keep using it. A colleague mentioned that this could be done through the Exchange Control Panel (ECP) by detaching it from the old user and connecting it to the new user. But from what I've read, it seems this can only be handled through PowerShell commands like 'Disable-Mailbox' and 'Connect-Mailbox'. Am I missing something here, or is my colleague overly optimistic about ECP's capabilities?

You can indeed connect a deleted mailbox through both ECP and PowerShell. Just Google 'exchange 2019 connect deleted mailbox to new user', and you should find clear instructions. Just ensure you're on the right path based on your Exchange version.
Actually, you might be able to do simple connect operations in ECP after disconnecting a mailbox from its original user. If you're connecting to a new AD object, though, it's safer to use PowerShell for this kind of operation. Just to confirm, it seems you're on the right track with PowerShell.
Is there even a real question here? You already laid out the commands, it seems like the answer is right in front of you!
I've heard that you can connect a previously disconnected mailbox via ECP. If you go to Recipients > Mailboxes, there's a 'Connect Mailbox' option in the dropdown menu. However, I don't think you can use ECP to disconnect a mailbox in the first place, so it's a mixed bag.
It's not just about the commands, it's about confirming my colleague's claim!
