Outlook is incredibly slow when asking to open an additional mailbox

Hello all,
My problem is with Outlook 2007
My company has a Mailbox called Customer Support
When I as outlook to open this new mailbox (in addition to my personal one), then outlook is incredibly slow.
(More then 5 minutes to open...) Then browsing the mails in customer support is also very slow.
When I remove this additional mailbox, I don't have any troubles.

This is something new, as I always had this additional mailbox, and I had never this problem.
Also, some other people have this additional mailbox open without any problems, so I guess this must have something to do with my profile.
Any idea to help me ? Thanks in advance....

does the customer support mailbox have alot of email in the working folders (inbox, sent items, deleted items?) if so that will slow it down.  do you see any outlook popups saying that outlook is retrieving info from the exchange server?

are you in cached mode? try coming out of cached mode.

Hello opie6373
The customer support has many emails thats for sure....
But the other people accessing the same mailbox do not have this problem.

No popups are coming.
Also, when turning off cached mode, it is even worse...
yeah, i'd remove you exchange account from outlook and readd it

did it work fine before with outlook 2007?
Yes it worked fine until some days...
Don't know what happened...
I will try to recreate my account, and if needed, I will reinstall my computer
Thanks anyway opie6373
how about reinstalling outlook ?  anything in your error logs?  any microsoft updates recently?  or other changes?
Well, just reinstall my computer.
OS + Office

Exactly the same problem. So this must be on the Exchange 2007 server side...
Ok I have some news.
It is probably a Vista update that is causing this problem.
I have tested it on an other computer as well, using Windows Vista, with same level of update
And the problem is the same.

Tested on a Windows XP with Office 2007 : no problem....

SO many thanks to microsoft and there nice updates.... but these kind of updates, I would rather forget them....
does the update support removal?  do you use wsus to manage your updates?  if so i would uninstall the update and then change the approval in wsus (unless it is a critical security update)
OK find out what was causing the problem.
On the exchange server, I passed for a couple of days this command :

netsh int ip set chimney DISABLED
This was causing all the troubles

netsh int ip set chimney ENABLED fixed it immediately.

So hope this can help others.
