Determing if there any live users left on Exchange 2007

Posted on 2016-08-31

Got a co-located system with both 2007 and 2013. We've migrated nearly everyone we wanted to 2013 now.

BUT, we didn't want to migrate old users or disabled users. However, it appears our plan wasn't that good.

Is there any way to tell (from message tracking logs maybe) whether there are any users out there who are still on Exchange 2007 and using this to send email?

you can open smtpsend log files, to see if anyone is sending email from that server.
It has time, so you will be able easy to see who and at what time did use that server to send email.

As for users, you can always simple query each database to see if there are some mailboxes left via:
Get-MailboxDatabase -Identity "Server_name\StorageGroup01\MailboxDatabase01" | Get-MailboxStatistics | ft DisplayName
Get-Mailbox –Server “ServerName” | ft DisplayName (think this one works as well).
Off course you can simple open exchange console, add server in view, and see if there are some mailboxes left on it.

Thing is we know there are lots of mailboxes left on the old system. The idea was to leave the old  unused ones (they were never deleted).

So a list was made of all active users but we still think there are some used ones on 2007.

maybe this can help you: Get-Mailboxstatistics  | select-object DisplayName, LastLogonTime
Command will list last time user has logged to mailbox.

You should check those smtpsend logs, which are not hard to understand, since it will tell you if some1 has sent email, and in what time. By that you will know if some1 is still sending email via it.
