My PS one line looks like below: C:\>Get-StorageGroup -server excserver01 -OutVariable SG | Where-Object {$_.CircularLoggingEnabled -eq "True"} | Get-MailboxDatabase | Where-Object {$_.StorageGroupName -eq $SG.name } Idea is that I like to dismount all databases which have circular logging enabled. I have used Get-MailboxDatabase cmdlet to see which databases this cmdlet returns. But the list is empty. When I can see correct databases I can change Get-MailboxDatabase to Dismount... -- Petri

-OutVariable parameter at first command will enumerate all SGs in that server. Try this... $CLEnabledSG = Get-Storagegroup -server ExcServer01 | Where-object {$_.CircularLoggingEnabled -eq "true} you can see the output of this command in this Variable $CLEnableSG. $CLEnableSG | Foreach {Get-mailboxdatabase -storagegroup $_.identity | Dismount-database -confirm:$false} Let us know how it goes.

That does the work, but as for shell practice I would like to see this on one line, without extra variables. -- Petri

well then try this... Get-Storagegroup -server ExcServer01 | Where-object {$_.CircularLoggingEnabled -eq "true} | Foreach-object {Get-mailboxdatabase -storagegroup $_.identity | Dismount-database -confirm:$false} Just removed the variable.

Greaaaat !!!!! Big thanks to you ! I have feeling that "Foreach-object" might be needed in future as well :D -- Petri
