Exchange email clients won't connect after upgrade from 2007 to 2010
A few days ago I received an email that said my mailboxes would be upgraded from Exchange 2007 to 2010. Since this morning, none of my clients for any of my mailboxes can connect. Outlook and iPhone email was working fine before. Outlook autodiscover doesn't work to reconfigure the mailboxes either. The only thing that does work is webmail, which is fine for a few hours but I really need things working the way they were! The upgrade email said that I would receive another note when the upgrade was complete and that I might have to take some additional steps. I never received an email. What steps should be taken???
