I have been using Lion since it was released with no issues as far as Mail was concerned. Today, I can't receive mail from MobileMe. I can send mail through MobileMe, I can send and receive mail from Gmail. I can send and receive mail with my iPhone using both accounts. The only issue is on my Mac I am not getting mail from MobileMe, the wheel just spins and spins, it never stops and never gives me an error telling me whats wrong. I have quit Mail, it wouldn't reopen properly so I had to Force Quit a couple times. I restarted my Mac, I checked the account settings in Mail and I checked the MobileMe settings in System Preferences. I also checked me.com and the emails are there. Any thoughts on what is wrong? Not sure what was going on, but after trying for a couple hours, the mail is working again.
