Exchange 2010/2007 CAS coexistence with Enterprise Vault
We are migrating our Exchange environment from 2007 to 2010. We have cutover our CAS connections from 2007 to 2010. In doing so, we lost the toolbar shortcuts in OWA. We have EV extensions loaded on the 2007 CAS servers but not on the 2010. It is my understanding that the client connections for OWA go directly to the virtual directory on the EV server. If that is the case I wouldn't think that it would matter if the 2010 CAS has extensions or not. In any instance if any of you have been through this scenario any assistance or guidance would be appreciated.
