I spent whole day today to figure out how to make both OWA and ActiveSync working properly. I can't make them working at the same time. This is what I test both of them from Exchange 2003 IIS management,
1. IF Let OWA working from http://mail.domain/exchange
, and user is able to log on and open outlook web emails without error, I have to configure authentication and access control on Directory Security for
a, Exchange Virtual server - Basic authentication
b. Public - Basic authentication
c. Exchange WEB - uncheck both Basic Authentication and Integrated Windows Authentication, and select the Enable anonymous access check box
d. Default Web site stop and then start.
OWA will be working perfectly without error. But ActiveSync stop and fail working.
2. If let ActiveSync work perfectly, I have to configure authentication and access control on Directory security for,
a. Exchange Virtual Directory - both integrated windows authentication and Basic authentication boxes check.
b. No Touch exchange Web
c Virtual Directory - Basic authentication box check.
d. Public Virtual Directory - both integrated windows and Basic authentication boxes check.
ActiveSync will be working perfectly, all mobile devices are synchronized properly. BUT OWA fail working and user getting access denied.
So, both OWA and ActiveSync are not able to work properly at the same time. We don't have this problem for past 8 years. The issue is the authentication between Basic and integrated windows, how to play correct roles for both OWA and ActiveSync working properly. Exchange 2003 server is suddenly not able to determine those roles for both OWA and ActiveSync.
Hopefully, you understand my writing for time I spent. I am wondering whether it is causing by Microsoft widows updates to the server.
Thank you and please help us to solve problems,
