FIX! HTC Mail App corrupt jpg or file "File cannot be opened because it is corrupted"

[OceanHome]

This must be an HTC mail app issue. I have the HTC Thunderbolt, and I setup the HTC Mail app with an Exchange account.

If my account settings are to never download an attachment, the first time I open an email, I'm able to download and open the attachment. If I exit the mail app, then reopen the email, now that the attachment has already been downloaded, it will give me the "The file cannot be opened because it is corrupted" error.

Initially, I setup the account settings to automatically download attachments under 1MB. If I do that, when I open the email, I always encounter this error and cannot view my attachments.

Is there a fix for this issue or an alternate mail app that allows Exchange accounts with push email?
