I have an Exchange server 2010 behind a TMG 2010, all was working fine OWA, ANYWHERE & ACTIVESYNC until the certificate expired.
I have renewed the certificate, ANYWHERE & ACTIVESYNC is working fine, I got an issue with OWA when accessing from outside.
1. The website is not available
2. 404 error
3. sometimes I got the trust certificate and 404 error
From the TMG I can access OWA on Exchange but not from external.
I even delete the rule & Listener and create a new one, issue persist.
note: I use a listener for each service.
In the TMG Logs, I created a filter on HTTPS, but I did not see my request coming in, I see for ActiveSync and others
Note: OWA is configured with FBA and in Exchange 2010 the Service FBA is started.
Thanking you in advanced
