Twice now on my Droid X and once on my mom's Droid 2, the email has stopped automatically being retrieved. I haven't changed any settings and the phone is set to check for new email every 15 min. Same with my mom's. So far the only work around has been to delete all email accounts and then re-add them. Last time I did this it worked for about a week before it stopped getting the email automatically and I had to resort to manually retrieving my email. What is causing this and is there a fix?
