We have a brand new exchange 2013 install. it's all default install and mail is flowing with a go daddy cert. OWA, mobile and Outlook 2010 is working fine…mail is flowing fine…
There are a few (about three) Windows XP boxes in the building. They run Outlook 2010. ALL of my XP users with Office 2010 get repeated credential prompts and I cannot set up the mail.
All of my Win 7/8 machines with Office 2010 setup perfectly, with no problems. It's only my XP machines that are giving me grief.
I hate to start jacking with my Exchange authentication credentials without knowing what my problem is. So, anyone have any idea? Do I need to go POP3 with these XP machines or maybe IMAP?
Any help would be appreciated.
