Hi,
We have an TMG 2010 that is running on a server 2008 R2 that also is our Exchange edge and also has FPE 2010. we access our OWA that is behind this TMG server, laatly I come accross this issue, when I access the owa link it gets open then when I try to loggin to the owa rendomly see this error in browser:
Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202)
streang thing is when I close and open the web browser then I can login to the OWA without any issue. we use this publish rule for more then 2 years and never has any issue.
I did also run the logs on the TMG server and at the same time I get the error in the browser get this error on the TMG server:
