Hi folks!
For everyone like Clean-MailboxDatabase, this cmdlet has been decommissioned. Now, you will can use Update-StoreMailboxState…
Update-StoreMailboxState -Database MDB01 -Identity 4a830e3f-fd07-4629-baa1-8bce16b86d88
To get information, you can run the follow command:
Get-MailboxDatabase | Get-MailboxStatistics | ft displayname,mailboxguid,database,disconnectreason,disconnectdate -wrap -autosize
At the ECP, you can see Connect a mailbox to reconnect the mailbox.
I hope you enjoy!
