I've experienced the same thing with Outlook clients, but under only two conditions:
1. The mail server's CPU utilization is VERY high. 2. The client's internet connection is unstable. For me, I solved 1 by upgrading their mail server from a P100 (it was also running SpamAssassin and AV software). 2 was fixed when the telco went to the client and fixed their DSL connection. So far, I've only seen Outlook exhibit this. (It seems to be able to download the email, but then can't issue a DELETE in those circumstances) Rick Quoting Ron Culler <[EMAIL PROTECTED]>: > We are seeing a strange problem with some of our pop email clients.
