When I first got my phone a couple of months ago I was able to sync OWA with no problem. The one day it magically stopped working. I tried to remove the account and add it again but I've never been able to get it sync'd again. My boss who has the same phone is also having problems with it however my coworker has it on his ipod touch with no problems. I've called IT and they say they have not changed anything so I have no clue what to do next.

I've tried two URL's and both give me the same error message: 

https://mailtor.ttslnet.com/exchange and https://mailtor.ttslnet.com/exchweb/bin/auth/owalogon.asp?url=https://mailtor.ttslnet.com/exchange&reason=0 

once I put my user/pass in and it tries to connect it comes back and says "unable to establish a connection to your outlook web access account using the username, password and server address you entered. Please use a PC web browser to log in to your account, then enter the same account settings on your phont to complete setup."

the one thing I have noticed is if I try to access  https://mailtor.ttslnet.com/exchange through firefox it tells me the certificate is bad however the other link works fine in firefox. Not sure if that may be the cause of the problem or not.

thanks for your help!
