Need help setting up Comcast email through Exchange
I'm having trouble setting up my comcast email on my iPhone through the Exchange. It looks like everything is setup fine. I've even received some emails on my phone, but then they suddenly disappear and it says I have no mail. Another person in my office is having the exact same problem. Comcast Business sent our office an email that they had upgraded from Microsoft Exchange 2007 to Microsoft Exchange 2010. Any suggestions?
