    Question

  • 1. I already Enable OWA in the user exchange profile.
    2. User enable log in OWA in his own PC.
    3. I use my PC to test the user account, it is the same error msg.
    I am able to log in my OWA in home and office, so confirm it is not the user PC setting

    problem.


    Problem is when the user login from other computer, no matter office or home, it will give

  • hi,

    is there a login restriction for your workstations? maybe that worstation can only login on this machine in active directory.

    please check login restriction policy.

    open active directory management console,

    select the user - right click and properties. go to Account Tab and click Log on To button. check the status of Logon Worstations.

    if there is a logon restriction here please add here your mail domain for example: cozumpark.com

    and then try again to open OWA...

    and also be sure that the net logon service is running properly.
