We have installed the WAE's (4.01) on several sites and, even though, it's working well by and large, we are experiencing some problems with e-mail. ....The e-mail in question is Microsoft Exchange 2003 and the problem manifests itself in very slow opening of the Exchange client, and, in some cases, even coming to a complete halt...Both, the client site and the server site have WAE installed. When we disable the WCCP, the problem disappears, so the WAE looks like the culprit... Yet, I am a bit skeptical because first, I have been told that no e-mail traffic was going to be optimized and, secondly, I did not see the port 135 (outlook client) among the ports(protocols) in the default policy. Can someone please shed the light on what could be going on here?
