I use the default Email app with my work's Exchange email. I haven't had any problems for the three months I've been using it until yesterday. I got a new email notification, I went to open it, and email force closed (no "wait" option, just FC.) I tried it again--same thing. Restarted phone--same thing. Pulled battery and restarted--same thing. I haven't installed any new apps or done anything that would make it do this. I can still navigate through folders in Email, but I can't open any messages. What do I do? Can I somehow reinstall the default email app, or do I have to do a factory restore? Right now I'm using the trial version of Touchdown, but I really don't want to have to pay $20 for it when the default app worked fine for me and was free.
