OWA - Outlook Web App isn't available.
Posted on 2014-04-23
We are experiencing an issue with OWA. When trying to login through OWA, All users receive "Outlook Web App isn't available".
I'm busting my head against the wall trying to figure out the cause.
One thing I did notice is that in IIS Manager under OWA -- each server has a different version. However, I'm not sure how this would have happened
EX-02 (which is being pointed at for owa access) has version 14.2.298.4 & version 220.127.116.11 but seems like the latest version is taking over.
EX-01 has version 18.104.22.168
EX-03 has version 22.214.171.124
From Application log on EX-02
EX-02 has a mailbox on 126.96.36.199 server version. However, no Client Access server or front-end server with a matching version was found to handle the request.
Help is greatly appreciated!
