i have a disconnected mailbox that it's user deleted. Now, i want disappear this warning for that user in my disconnected mailbox. what can i do?

Hi, You can either reconnect that disconnected mbx with some AD user or just delete this mbx permanently if its of no use. For reconnect u can use Connect-Mailbox "Display Name of MBX" -User user@domain.com -Database "Mailbox Database" For deleting the disconnected mbx u can use get-mailboxstatistics -database 'MBXServer\Storage Group\mailbox database'| Where{($_.DisconnectDate -ne $null) -and ($_.DisplayName -eq 'DisplayName') }| foreach {remove-mailbox -database $_.database -storemailboxidentity $_.mailboxguid } You have to modify object names in the command accordingly.
