Question : Exchange BIS sending issues

Blackberry on BIS with OWA on in-house Exchange 2007, We have problem sending BIS email The problem usually comes when replying to emails and when you open the unsent email (marked with a red cross) the status reads "Message included an invalid address".

The user can receive mail and send new emails fine but as soon as they want to forward or reply to a mail i get a red cross and the error message "Message included an invalid address".

I have tried deleting and setting the accounts up again, resending the service books, ran the firmware updates aswell as the desktop manager update with no luck. Anybody have any ideas how to fix it?

the second question is, is there a setting in exchnage that i have missed or some permission that i need to change or is it something the sp would have to sort out?

Answer : Exchange BIS sending issues

yes, you've got what i mean.. well, at least that is the case with my organization at the regional level. afaik, there is no solutions for this from rim yet.
however i have been told that some users are forwarding their email to gmail, so that they can send replies from gmail. i haven't try it myself though.
