in "disconnected mailbox" i have three entry for the same user and i have , for same user, mailbox active. How to "purge" the disconnected ? without remove the functional ?

Not sure what you mean by remove without remove the function. The mailbox is in disconnected state, it has no more "function" per se. However; Get the maiboxguid Get-MailboxStatistics | where-object { $_.DisconnectDate -ne $null } | Select DisplayName,MailboxGuid Then delete. Remove-Mailbox -Database <Database-Name> -StoreMailboxIdentity <MailboxGuid> -confirm:$false James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi, You can try this: PS>$store= Get-MailboxDatabase "<server_name>\<Storage_Group_Name>\<Mailbox_Database_name>" PS>Get-MailboxStatistics -database $store | where {$_.disconnectdate -ne $null} | foreach {remove-mailbox -database $store -storemailboxidentity $_.mailboxguid} Best Regards!
