I've read about this problem, just wondering if there were any fixes. We have a squid reverse proxy in from of OWA Exchange 2010. When a client connects through the proxy to the full/enriched OWA version there is about a 5 minute pause before everything starts working. After than, everything works great. If you sign-out and back in, you are still fine, unless you clear your cache, then you get the pause again. The light versions of OWA work fine.
Squid version is 2.7.9_1 -- Rick Chisholm Systems Administrator Parallel42
