I have my office's Exchange account on my mail app, and it seems to be running well. I tried K9 but didn't like the way the .ics calendar items wouldn't get added to my calendar, so back to the stock app I went. But, when I try to add my yahoo and gmail accounts to the stocker I get "503 80318: User has invalid status". It does the same for both accounts. I can get my email from the native yahoo and gmail account AND from K9 so its probably something wrong with the stock mail app. I have rebooted. Trying a battery pull now, but any ideas would be appreciated.
