Exch 2013 and 2007 coexistance, unable to login to OWA

I have a 2007 server and just installed a 2013 Exchange server.  Both sit on a 2008 R2.  After installing 2013, I created the new mailbox like the M guide stated.  When I go to OWA however it says that "A mailbox couldn't be found for NT AUTHORITY\SYSTEM."  I can however log in to ECP with the Admin account.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Been through that one over and over, thanks.  Found that the only way to log in to ECP was if the server itself was a member of the Org Mana group, but that only logs in to ECP as the NT AUTH/SYSTEM account. Once you remove the server from the OM group ou can't log in to OWA or ECP.  Tried rebuilding OWA and ECP virtual directories with no luck.

I have not encountered this untill now but it seems that recreating the virtual directories is the way to go here:

Neither of these comments are the solution.  I have reset both virtual directories and have tried tcp ecp/ owa and owa/ urls but always endup with the "something went wrong" page and reference to NT AUTHORITY/SYSTEM account.
