I have looked all around and nobody seems to have this problem, but when I send and receive email on my Axim X50 with the WM5 upgrade, the header shows up, but no email content at all. I have tried all the options regarding headers, full content of the message, etc., but still nothing. If I send email from my Axim then the message arrives without any content also. Weird, huh, I know!

Can anyone please enlighten me as to what I could be missing?

This is a problem with WM5 after you have performed a restor. The only solution I have found is to delete the email account and then add it back in as a new account. If that does not solve the problem then it was back to a hard reset.
I have had the problem many times after a restore from a backup using the Dell supplier backup software in WM5. Deleteing the account and starting over usually works.
