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