Everytime a user opens Outlook 2007 or 2010 this box(attached image) pops up asking to verify the Microsoft Exchange server name and mailbox name. The users information is alutomatically filled in and clicking ok makes the box go away but it will eventually pop up again or when outlook is closed and re-opened. Any ideas on what is causing this? Let me know if you need any more information. This was not happening intially but around the time Autodiscover was configured this starting showing up.
One Exchange 2010 server recently migrated from old 2007 server to new 2010 server. All users have been moved over to 2010. 2007 is no longer used.
Happens to all users on both Outlook 2007 and 2010
Exchange 2010 server holds mailbox, cas, and hub role.
Server 2008 R2
