I have gmail, comcast mail and corporate email (MS Exchange ) on my Droid. This morning, something strange happened when I opened my email. It showed sender and title from my corporate mail , but body from gmail or the other way around. It seemed all three accounts were all mixed up. I deleted all of emails in my gmail acct, but it continued to show the body of gmail paired with comcast or corporate email title. Strange... I finally reset all mail accounts and re-synced. It works fine now.

The other thing is, I think this is a known issue, when I forward a corporate email (Exchange) to others or my own gmail or comcast, the forwarded text message is all garbled. I hope they fix this problem.
