According to documentation and advertising the 7520 is supposed to be able to read MS Office attachments but mine doesn't. I would also like to view pdf files. I'm not interested in editing the files just read them. Am I don't something wrong or is the documentation wrong?

Are you on BES, or BIS?
What version of BES or BIS?
Also, what version of the handheld software is on your 7520?

I'm on BIS. Not sure what version however I just sent a test email with a small word doc attached and it worked. I think either I didn't wait long enough for the other attachment or maybe it was too big. Do you know what the size limit is?
