Hello everybody

We have a performance problem with Outlook 2003 clients which have huge
mailboxes.
When the user opens a folder the connections to the server seems to fail. It
can take up to 5 minutes until outlook responds again.

The mailbox is stored on our exchange server 5.5. Both (client and server)
have enough ressources.

We had to deactivate the cache function of outlook because the mailboxes are
sometimes more than 2 GB's. We already deactivated the instant messaging
function and the virus scan.

Did anyone see different problems?

Thanks for your answers.

Jean Daniel
 
The bigger the mailbox, the more resource load when you open it. Any reason
you don't have mail quotas in place? My default is usually 100MB, but of
course your mileage may vary. What's your network setup? Fast switched
Ethernet? Anything else running onj your Exchange server?
 
Unfortunately I'm not allowed to tell my boss what he needs to do ;-). So
that's why I cannot set quotas on some mailboxes.

Our network connection is always 100 mbit/s / full duplex. Network problems
cannot be the problem as the mailboxes run well under outlook 2000.

We have some other applications on our exchange server. This cannot be the
problem as the server is not busy at all and it runs fine under outlook
2000. There has to be a difference how outlook 2003 connects to the exchange
server.
