We are using an ISA 2006 Edge firewall with ActiveSync, OMA, And OWA published with SSL. We have one BE Exchange box which is running 2003 SP2. When trying to connect with mobile devices we are getting errors (Palm Treo and Windows Mobile 5 device) such as unauthorized connection and username/password invalid. All the certificate info looks correct and I can see the connection being approved by ISA 2006 publishing exchange rule I created. Our OWA works great. I suspect IIS or Exchange but do not rule out something in ISA and have hit a snag . Can anybody offer some good suggestions?
I set this up in another network identical to this way and it works great with OWA and ActiveSync.
Well this is a strange thing. I have deployed 2 of these. Our in-house network has had no problems with my Palm Treo 650. I did not install a certificate on my Palm. Our OWA and ActiveSync work great together and there has been no problem using the CA and same publishing rule. In my client's network we have tried my Palm and his IPAQ (with the cert installed). He keeps getting prompted for a valid username and password and I am getting the http 401 error. I have tried everything I can think of or have read short of creating a second Exchange virtual directory. I know I should not have to do this.
Ok...I have resolved the problem. I was down to reloading each part of the equation. I started by deleting and recreating the Exchange virtual directories in IIS. As luck would have it this was my issue. As soon as the recreated directories were in place the ActiveSync started to work (as well as OWA - all on the same listener).
