I have a user that is using a BB 7250 with a BES 4.0. When they reply to emails or try to send emails hey have a red x where the check mark usually is. Has anyone else seen this behavior before? Whow would I correct it?

Thanks

Most of the time this is only with Replay and Forward. Not with new composed emails.
Why?
The orginal email is not anymore in the user his/her inbox, so the BES "can not find" the orginal email.

Look insite the email with the red X and scroll-up in the header you read the error message.

I just sent the user an email and when he replied to it she received the red x again. Any ideas? I haven't been able to ask her to scroll up to see if there is an error message.

Could it be caused by the users mailbox being full?

another thought might be the network might be down at the time the message was sent or the person's email addy was wrong. Could be a number of reasons for the transaction error.

Open the message that failed to send. Scroll up to see the message status. What does it say?

Has this user ever been able to reply or forward? If so, try deleteing the Desktop [CMIME] service book. Then immediatly undelete it. The BlackBerry will restart the slow sync portion of the activation process. Just let it bee until it completes.

I experienced the same problem on my device. Tried most of the suggestions on this forum but ended up doing a handheld wipe and an enterprise activation.

I found that everytime I plug in my bb to my PC, my desktop(cmime), desktop(cical) and desktop(sync) settings would change. I am set up on BES but everytime I plug in my bb, the service book settings change to settings on the desktop manager. I have reinstalled the DM several times ensuring I configure it for sync / work thru BES. This did not help.

Besdides never plugging in my bb to my PC, I do not seem to know how to prevent this from happening. Any help would be appreciated.

Try deleting the service books and resending them or just resend them. Also you can register with the network from the device. If the user is next their computer then have them regenerate their encryption key. If all fails then wipe and reactivate.
