Poor performance from Outlook 2007 against Exchange

[James P. Clark]

I have been struggling to get Outlook 2007 to state of usefulness against my company's Exchange server. So far, the poor performance renders it absolutely unusable. I run Outlook 2003 (on Windows XP Pro) on a different computer against the same Exchange server with no problems, using the server-based mailbox. With Outlook 2007 it will take over 10 seconds to bring up an email message, usually going into "(Not Responding) mode" with a "Outlook is trying to retrieve..." popup on the taskbar. I'm running under Windows Vista Ultimate with the latest patches obtained for Vista and Office 2007 via Windows Update. I've turned off RSS feeds.

Hello James,

There are couple of reasons for the slow performance of outlook.

Add-ins
corrupted outlook files
third party programs.
corrupted installation files of outlook

start>run>outlook /safe>check the performance of outlook.

If this one works then it might be an Add-in issue.
Start>run>regedit>
In the registry editor window >HKEY CURRENT
USER>software>microsoft>office>outlook>addin>right click and click on delete
Hkey local machine>software>microsoft>office>outlook>addin>right click and
click on delete.
Please be cautious with the keys you are deleting.
letme know if this resolve the issue.

I tried all of the following:
Diabled Add-ins
Ran Help->Office Diagnostics
Turned off RSS feeds

None of these improved the performance, but I did find the solution and will
post it here for the benefit of others. It was not related to Outlook 2007
at all, but rather the new TCP/IP stack in Windows Vista. From this helpful
site:

I found this tip:
<<
Mike Bisson has posted a comment on Tim Anderson's blog that offers a fix
for Outlook 2007 performance issues when running on Vista:
Go to Programs -> Accessories and right click on command prompt and select
"run as administrator"

Then type in the following:
netsh interface tcp set global autotuninglevel=disable
This action brought the performance level of Outlook 2007 to that of what I
was used to with Outlook 2003. Good luck to all with this problem!
