Hello!

In production I have two cas servers. When I run Get-CASMailbox | Fl Name,ServerName see two servers.

Why exchange use two cas server? What is a parameter ServerName for casmailbox users?

Server Name is really not useful with Exchange 2010/2013. I would look at at database instead to figure out where the mailboxes are. ( you can figure out which servers those Databases are active on from there with get-mailboxdatabasecopystatus

Example:

Get-CASMailbox *ma* | Get-Mailbox |FL da*, name

Get-MailboxDatabaseCopyStatus <Database listed above>

Thank you Andy! May be it used for point to preffered CAS server when user connect to mailbox through NLB/HLB balancer?

I think its more likely just stuff they need to clean up within the Powershell code.  :)

Thanks Andy!

Where are so many stuff need to clean up!!! It make me confuse.
