I've read the article at http://technet.microsoft.com/en-us/library/bb430760(v=exchg.141).aspxon "Rename an Outlook Web App Web Site". That did not allow me to change the urlaccess from "/owa"to "/anythingiwant". It only removed OWA, then re-added it.
I even added a parameter at the end of the shell command "New-OwaVirtualDirectory" called "ExternalUrl", but that still created only an "owa" virtual directory in IIS.
Should be simple I hope! Lots of different answers, but I can't find this particular answer. Can anyone please help?
