Hi,
I hope someone can help me. I have a situation where OWA does not work internally. OWA is not used internally very often so I can't be sure when/what caused this but it seems to have happened since I updated our soon to expire Exchange certificate.
When browsing to the internal URL (
https://exchangeservername/owa) I get the message that the certificate has been revoked. We have two on-premise HT/CA servers and this happens with either of them. OWA works fine externally as does Outlook Anywhere / ActiveSync.
If I run get-exchangecertificate in Powershell it shows all the correct SANs and is enabled for all services but the status shows as "Invalid". To test things, I created a self signed certificate and enabled it for all services. This fixed the problem of internal OWA access but of course broke external access / ActiveSync etc. The intermediate certificate has been installed correctly (I believe).
Does anyone have any ideas? There may be some info I have missed out so just ask if you need to know anything else.
Thanks in advance...
