We are migrating from Exchange 2010 to Exchange 2013. We completed the install of Exchange 2013 - CAS and MBX on two separate servers - without any issue. I was then able to create a mailbox on the new 2013 CAS via the ECP. However, when I try to edit my CAS server for Outlook Anywhere, I get the error "An IIS directory entry couldn't be created. The error message is Access is denied. HResult = -2147024891"
The same error shows up when I try to run "get-owavirtualdirectory" in EMS. Although it does show me the OWA from my 2010 server.
In virtual directories, I have a lot references to my current 2010 server.
Both the 2013 servers have Exchange Trusted Subsystem group added to their local Administrators group.
I've Googled this and I find a lot of references to Exchange 2007, but we don't have that in our environment. We do have an old server up that still has an old Exchange 2003 on it - but this has been inactive since we moved to 2010 and hasn't caused any issues at all. Should I try adding the Exchange Trusted Subsystem group to the local admins group of that server, or will that cause more issues?
Does anyone know what could be the issue here? Am I just missing some post-installation steps?
Thank you,
Sid
