I am running Outlook 2000 - every once in awhile on this machine I get an email that freezes up my outlook altogether and I have to get out of it via the Task Manager. I am able to log onto an XP machine on the same domain and use Outlook 2000 (same version) from there and the same message works fine. What could have happened to my outlook on the NT machine that would cause this to freeze? Virus scans have come up clean on this machine and it has all the proper windows updates installed. Any suggestions? Thanks!

One thing I have come across that does cause Outlook to hang is if there are too many messages in the inbox i.e. thousands. It's ok if you have folders in the inbox and they have thousands of messages in them, it's when they are in the root that the problem occurrs. On a machine with loads of memory Outlook may open fine, go to one with less RAM and it hangs. Just a thought.

Oh, another thing to try: If it works ok on one PC but has problems on another, delete the email profile in Control Panel and recreate it. That sometimes helps.

How large is your pst file? If it's over a Gig, I'd recommend compressing it and then see if that increases performance.

I've experienced this same problem...Turned out to be a corrupt calendar in a .pst file. I was able to import the same .pst file to a working machine and re-create the problem. when outlook would hang my CPU spiked to 100%. To fix my issue i re-exported my .pst minus the corrupt calendar and that fixed it. Sounds like something is corrupt in your .pst file or inbox. try moving the problem to another computer to see if something was corrupted. hope this helps

I read all these responses (I have similar problems) but how do you find out if you have a corrupted pst. file? I have run detect and repair and it shows no problems. I have reloaded Outlook and still it hangs when I type too fast writing an email -- also when I hit "send" which does auto spell-check. This is driving me CRAZY since I've lost a lot of emails I've written. Have to go thru taskmanager as one of you described and then I lose the message when it closes down. Help!

i doubt it's a corrupt pst file because the pst file is located on the exchange server and not locally, but it works on one machine from the other. it's not a virus. almost thinking of just reinstalling office - think it's a bug in outlook or something maybe, what do you all think?
