One is on the same domain running TMG 2010 and is registered on the domain. One of the DCs runs exchange 2007 sp1 as a Single instance installation. All working fine with the exception of active sync. OWA is set up and running perfectly both internally and externally. Active sync is not working however, either from externally using any phone, or from internally using an emulator. Http 500 error is being show regularly, but there are no helpful entries in the IIS log files. I have used EMS to remove the active sync virtual directories and recreated them, but no change. I have also gone into the GPs and ensured that inheritance is not the cause of the problem. Grateful for any suggestions as to how to get it going… They are quite reliant on mobile access these days!
