Following a migration from 2010 to 2013 we are finding that for a number of users the old exchange server address stays in the mail profile (control panel -> mail -> e-mail accounts) which causes Outlook not to load.
We are able to go into control panel -> mail -> e-mail accounts and change this manually to the new exchange 2013 server address but we have quite a number of users and don't really want to do it manually.
Shouldn't it be updating automatically and if so why is it?
