Yesterday I noticed that my emails from my phone were not getting sent. Today I noticed I had a bunch in my outbox that said sending. I have the sync turned on and all my other Google apps sync (Calendar, Picasa, Contacts) but gmail never updates. I can't force it to send and receive either. And I can't remove my account to set it up again without doing a factory reset. Any ideas why just my gmail is not syncing anymore? BTW I tried to uncheck all sync options turn off phone and back on then check them again without any luck.
