Hi,
Has a very strange problem, that I cannot find out.
We have 2 site solution, Exchange 2010 CAS in both sites. And Exchange 2007 in only one site.
We have an calendar sync tool that uses impersonate and we also have som MAC clients. The strange thing is that EWS does not work when query users on Exchange 2007 using one of the Exchange2010 CAS server. When we specify the other server it works like charm. Same thing with MAC client.
Config is the same, and when on Exchange2010 both servers work.
Any suggestion?
