Hey there, I have multi role exchange 2013. in my "Exchange Back End" website I have a Rpc virtual directory. I understand the physical path for this VD is %windir%\System32\RpcProxy. My issue is that this keeps reverting back to C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\rpc which is the same path as the "Default Web Site" Rpc virtual directory. When it does this Outlook breaks. So I set it back to %windir%\System32\RpcProxy, outlook works again, then after a few minutes, it reverts back to c:\program files... and outlook breaks again.
help?
To clarify, I have included two screens below. The first image shows the physical paths after I change it. Then about 5 or 10 minutes later, the path reverts as seen in the bottom image.
