I have determined that one of my three email accounts appears to be causing the email app to crash when the Fetch New Data process runs.
I discovered which account was responsibe by first turning them all off. I then turned the first one back on, opened the email app, started a new email and waited for the Fetch process to run (the setting for this on my iPad is 15 minutes). After waiting for a Fetch cycle to complete, I turned off the first account and repeated the process with the second one and then the third one.
It turns out that the first account in my list is causing the email app crashes. By turning it off the other two accounts will not cause a crash during a Fetch.
I have attempted to fix the first account without success. Unfortunately it's my primary email account. So far I have tried the following:
- I deleted the account on the iPad and allowed iTunes on my Windows box to rebuild it through a sync.
- I deleted the account on the iPad and rebuilt it manually on the iPad.
I don't know of another way to recreate the account. It's a pop account with nothing unusual about it and it worked fine before the iOS 5 update. Incidentally, the iPad would not accept the settings during the manual rebuild but allowed me to save the account. Once it was saved I was able to edit the Advanced settings and set Authentication to Password and the account would then send and receive emails but it continues to crash the email app during a Fetch unless I turn it off.
I would be delighted to hear from anyone who has successfully overcome email app crashes. I would also appreciate any suggestions about how to successfully rebuild this account.
A special thanks to Austin Rob for his comments above. BTW Rob, I tried adding a free app but it didn't help.
