Our exchange Outlook Web Access server started giving us the following error this morning:
http 400 Bad Request (Invalid Hostname)
I have followed all the documents I could find on experts-exchange and nothing seems to work.
owa/exchange = same error
ipofowa/exchange = same error
We have disabled SSL on our server and it still doesn't work.
We currently have a backend cluster with a front end-OWA and a bridgehead server.
