    255.255.255.0

    no getaway 

    internal DNS:

  • Hi,

    Do you re-configure rule for OWA and ActiveSync service on Port 443?
    You can check the below document to find more information about TMG and Exchange integration:
    Publishing Exchange Server 2010 with Forefront Unified Access Gateway 2010 and Forefront Threat Management Gateway 2010

    For external access, you can run ExRCA to test the connection for ActiveSync service.

    Best Regards,

  • Hello,

    I solved the problem , the issue was from  imported rules ,  deleted  all the rules and create it one by one from scratch, working fine.
