It's weird really, a few days ago I started getting errors with the mail app and my hotmail accounts, something about the certificates not being valid, and hen afterwards it tells me that the username or password for my email is incorrect. Now I know my password is correct as I logged into hotmail through safari. Anyways what I did was I did a restore and it got fixed for a few days. Now it's happened again, its really annoying the crap out of me. I have it set to check for mail hourly and have my ipad constantly connected through wifi. Any idea on how I can fix this guys? Btw it only happens for my hotmail accounts, my aol and gmail accounts are fine.
