Hangs in connection to Exchange 2003

We have a 45 node domain and for mail we use Exchange 2003 with Outlook 2007.

Often some of our clients get long delays in connecting to the server. The Outlook icon in the system tray shows a egg-timer and sometimes the delay can be for as long as 2 or 3 minutes.

Our network is Gb and there are no bottlenecks between these clients and the exchange server. The server is a stand-alone exchange server with no other apps and is a 3Gb Xeon HP Proliant DL360. I am sure the issue is not with our network of server hardware.

Has anyone ever seen this behaviour or have any possible suggestions as to what may be causing the hangs?

    How big are the user's mailboxes? Do you have cached exchange mode enabled?

    It may be that either the mailbox is very large which means a large amount of data is being transferred across the network, or if you don't have cached mode enabled it could be downloading/loading large attachments or something.

    I doubt this is the case since you have a gigabyte network, is that to the desk though or just your backbone?

    Ran both tools a couple of times and followed various recommendations supplied.

    Our hang issues were completely solved as well as fixing a few other issues (such as slow address autocomplete etc)

    Great solution.

    Thanks #1!
