What web apps are you trying to access? Remember that the apps do need to meet certain browser functions and requirements that may not be available on the BlackBerry Browser.
I was trying to access Excel and OneNote. I'm not sure what browser functions are required.
I tried to login again to get the exact message, however, I now get an error when I try to login from my BlackBerry. "An unexpected error has occurred during login. Please contact your administrator." I have rebooted the phone, but still get the same error. Any suggestions?
Grant W, Try installing Opera Mini on your BB and give that a try.
