Hi

One of our tech guys created a user account on-premise AD, enabled the mailbox on Exchange Online (powershell) and then converted the account to a Room mailbox (powershell). My question is without disrupting a live room account, can i delete this or is disable the only option?

I found the below link but doesnt mention about what to do with the account, ie delete. https://learn.microsoft.com/en-us/answers/questions/642282/convert-user-account-to-room-resource-account

Thanks in advance.

    If you delete it, the mailbox will be disconnected/unusuable. You need the corresponding user object for it to work, but you can safely disable it if you want.

    Hi, @Imran Shabir

    Vasil Michev's summary is accurate. I'll just make a few additions.

    If you want to manage the mailbox without affecting the normal functioning of the currently active resource room, the best practice is to disable the mailbox instead of deleting it.

    Disabling the mailbox removes the Exchange attribute from the user account, but retains the account in AD. Deleting a mailbox deletes both the mailbox data and the user account from AD.

    Disabling a mailbox allows you to re-enable it when you need to. Deleting a mailbox can disrupt some meetings and affect users who rely on it.

    Disable mailboxes using the command:

    Disable-Mailbox -Identity "RoomMailboxName"

    Once you are sure that the mailbox is no longer needed in the future and will not affect any users, you can use the following command to delete the mailbox:

    Remove-Mailbox -Identity "RoomMailboxName"

    Hi @Vasil Michev and @Xintao Qiao-MSFT

    thank you for your responses.

    Would there be a way to offload on Exchange Online as its a Resource/Room calendar? i mean like deleting the on-prem essence or fully move it to Azure Entra/Exchange Online without the presence on local AD.
