I was having problems opening attachments using the Desktop Redirector with cingular edge network. I searched the board to avail for answers but I have since found the answers to this problem. I hope this will help future users:
YOU CANNOT OPEN E-MAIL ATTACHMENTS USING THE DESKTOP REDIRECTOR WITH MICROSOFT EXCHANGE SERVER! You can overcome this problem by activating a Blackberry Internet Service Account and using it as your e-mail redirector if you are using a Microsoft exchange server. You will first need to create the account, in my case it was with Cingular. You can go to https://webclient.blackberry.net/Web...ite=mycingular
to do this. You will be required to download the BIS software and then modify your Desktop Manager software through the control panel add/remove option. You will then have to get your system administrator to create a server rule which will redirect your email to your BIS account. You will then need to set up the rule locally on your machine. It took me a while to get this accomplished but it was worth it so that I could view e-mail attachments.
If this work-around is posted elsewhere I sure couldn't find it, I just thought this may help some newbs like me looking for answers.
