Blackberry Error forwarding and replying with Attachments

I am having issues with 4 Blackberry's that were working fine but now I am getting errors only when replying and forwarding emails with attachments.  Receiving and sending emails are no problem.  We are using BIS to SBS 2003 Server. Messages have Red X and error message is always "Message included an invalid address".  All 4 Blackberry's are different models and some are on Verizon and others on Sprint network.  Any help would be great!

Make sure that the Blackberry Attachment Service is running on the Blackberry Enterprise Server.

Ok, Sorry.  I have been away for a few days.  Thanks for the link -jonny-:.  Many of the fixes listed here are related to those users running Blackberry Enterprise Server. However, I did go through all of the suggestions just to double check.
I have created a brand new mail account on our server so as to make sure it is clean and setup my own blackberry Storm to access it and I still get the same problem as all the other users.  I have called and talked to Verizon (my own carrier) and they claim it has to be something wrong with our server.  The only thing I can think of is some issue with Message Labs.  All of our Exchange Email is filtered by Message Labs.   I have sent them a email but have not heard back as yet.  It seems that when I send emails from any computer or OWA , they all include the Message labs footnote in the email.  However when I send a message from one of the Blackberries no footer???????

Well, I have pretty much exhausted all possibilities and have decided to give up and host our email outside with someone that offers BES.  Thanks for your help
