I've tried this before, but did not solve my problem, I'm trying again. We are using IMail 7.02HF1 on NT 4.0 SP6a in a corporate environment. The 80 or so user machines are using Outlook 2000 and attaching to the server through a firewall using IMAP and SMTP. All email is stored on the server and each account has on average 100 Meg of email on the server. Some mailboxes are much larger. Our problem is that systems hang up with a "Fetching Headers" message in Outlook. Sometimes this will clear itself by exiting and restarting Outlook. There seems to be no correlation between server mail store size or number of messages in the Inbox. The problem seems to be increasing. We have other indications that the server is dropping communication with the client program. Messages are sent that Outlook does not move out of the outbox. Messages cannot be moved from folder to folder. The problem manifests itself even when Outlook is running on the IMail server, so I do not believe that it has anything to do with our network infrastructure. We do not have the same problem with Outlook Express, but have had problems with Outlook Express not showing all messages in the Inbox. I get a lot of send errors and net read errors in my sys log. Here is a sample from today's log (errors only). 07:12 00:01 IMAP4 (00000188) send error 192.160.56.123 10053 07:12 01:19 IMAP4 (000001d6) 192.160.56.223 net read error 10058 07:12 07:36 IMAP4 (0000012C) send error 192.160.56.23 10054 07:12 09:05 SMTPD(0C8E025E) send error 10054 07:12 13:00 IMAP4 (%1!08X!) send error %2!s! %3!u! There were 1400-2200 of these errors per day over the last three days. This problem has persisted on Imail 5.09, 6.06, and 7.02HF1. Each time I contact technical support, I'm told that the problem will be fixed in the next version/patch/hotfix. Well, it hasn't. In fact it is MUCH worse today (affects more users) on 7.02HF1 than it was on 6.06 a week ago. When I called Tuesday to try to get the problem fixed, I was told to wait for the hotfix and that would solve the problem, it didn't. They are now telling me that next patch will fix it for sure. I have my doubts. If anyone has insight into this problem, I would appreciate your thoughts. -cpc- Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
