Is this incorrect. On Fri, Apr 3, 2015 at 10:38 AM, Michael B.

I have a small pilot group in O365, no mailboxes on the Exchange 2013 servers remaining mailboxes are on the 2010 DAG. When I put one of the Exchange 2013 CAS/Mailbox servers into maintenance mode and reboot the server; what impact will the users experience in Outlook or OWA? -- T. Todd Lemmiksoo -- T.
