I’ve just set up our new SBS 2011 server and everything is working great for the most part.
My only issue is that when a new account is set up in Outlook the autodiscover gets the settings and then asks for the username and password. If I put in domainuser and the password it works great. If I try to use their email address it’s rejected.
I know I’ve gotten this to work once before with Exchange 2010 on 2008 R2 (not sbs) before but for the life of me I can’t remember how.
