I am using GoDaddy.com for my hosted Microsoft Exchange and using Microsoft Outlook 2007as my client. On one computer I setup my client without any problems. On my other computer, the exchange server will not accept my password. It is setup to autodiscover all my settings, which is done fine, it just seems to reject my username and password.
I can logon fine to my OWA (outlook web access).
Other notes: I have this set up on a Mac with Entourage, a windows mobile device with outlook mobile, and a windows machine with outlook 2007. This would be the fourth client with the setup.
