I have a customer where we have Unity 7 with failover Unified with their AD 2003/exchange 2003 environment. The Unity and Exchange servers are at one building and some of the users are located about 10 miles up the road. We have WAAS in place between the two locations. The users located where the Unity and exchange servers are located at are experiencing no problems with retrieving messages in their email. The users located in the building 10 miles away report when they go to open their Unified messaging email it is slow to open that as well as slow to open the attachment(actual voice mail) they do not have the plug in installed yet, and are using just media player. It shows in waas that it is being accelerate, but they continue to report slowness. I have them checking AD/dns/exchange versions and outlook versions. Any other path i can take here?
