Outlook 2007 Running extremely slow on certain users' PC's
Posted on 2009-07-06
We are running Exchange 2000 on a Windows 2000 Std server at present - due to upgrade to Win 2k3/2k8 and Exchange 2007 in the next 6-9 months.
In general, Outlook 2007 works well on our users' PCs (around 30 users in total). However, some users have complaints of Outlook running very slowly.
Symptoms of the problem are:
Taking 20 seconds to move between messages (including a 'not responding' screen)
Delayed response when typing or sending an e-mail
Taking 1 minute or longer to open attachments
This is happening on an almost daily basis, and after many hours of searching online I cannot find any causes. I've tried switching all add-ons off, reducing the size of the users' mailbox, etc.
The only 'temporary' fix is to switch Outlook into 'Safe mode' when it runs perfectly (although the reading pane sometimes switches itself off). Obviously, this is not an ideal fix as it does not store the users' settings and involves holding CTRL down every time I want to launch it in safe mode.
The only pattern I have noticed is that it only seems to be affecting the last 2-3 users who log on in the morning. In general, most people are in the office by 8-8:30am. If anyone logs in around 9am, they seems to be affected. I've looked in the exchange event viewer and cannot see any corresponding errors/warnings.
Has anyone else come across this issue before?
Does anyone know what would cause such an error and what can be done to resolve the issue??
Since starting here 18 months ago, this is the only recurring problem which seems to be affecting users and it's starting to frustrate me as in general I have quite a high 'first time fix' rate, but this one issue is really annoying to say the least!
Any comments are greatly appreciated.
Thanks in advance!
