Multiple Server 08 machines with Outlook 07 show the same problem...extreme latency to the exchange server. It takes up to 30-45 seconds to open an email of only 50kb. I've created my own virtual test environment and duplicated the reports. This is only on Server 08 x64 machines. Everything works perfectly on all other OS's. Process explorer shows nothing out of the ordinary. CPU load is minimal and there's no other tasks or processes running that would slow things down.
I had the networking team look at the situation and the connection is just fine to the machine and to the exchange server. Ping test are just fine.
Previously performed troubleshooting:
- Moved exchange data stores to different exchange servers (03 & 07)
- Disabled Anti-virus
- Updated Office with the most up to date updates and patches.
- Checked AD group policies for issues.
- Checked processes and server load.
Has anyone experienced anything similar to this? Microsoft phone support has been less than helpful.
