Message: [QUOTE="DarkOneX, post: 4715914"] As a network admin at our company I've ran across about 1-2 users per week starting to have this problem, and the first one was reported about 5 weeks ago, where they randomly cannot send emails in Outlook XP (w/ SP3). They may have a few stuck in their outbox, and if you try to send them it just hangs usually around 50% on trying to connect to SMTP on our mail server to send it. If you close Outlook and reopen it fixes it for awhile then starts doing it again. Another temp fix I found is if when it's happening if I go into TOols->Account settings->Advanced and on the ports tab I click Reset Defaults then change the incoming port back to 995 and SSL checked as it should be and leave the outgoing as 25 and no SSL as it should be then it fixes it again just for a bit then starts happening again. The ONLY 100% fix I've found thus far is to upgrade them to Office 2007 but that takes an hour a pop sometimes so that's not a good quick solution. I have been slowly upgrading users to 2007 but still have 80 or so to go and have been doing it on an as needed basis due to how much time it takes and I'm the only system admin here. It's definitely NOT an issue with a corrupt or huge PST file as this has happened even on small PSTs like a 150MB one. I know whenever PSTs for XP get up to about 2GB this happens and the emails get stuck and send over and over but this is NOT that problem this is different. I have a feeling that Microsoft might have released some Windows Update recently that started causing this since it's just so random and started happening for no good reason. I haven't changed anything with our mail server in a long long time so I doubt it's a server issue, seems more like some Outlook XP flakiness. Also FYI we do not use Exchange we use a Mirapoint mail appliance that basically supplies pop3/imap/webmail and it's a pretty basic setup and nothing has been changed with it recently to provoke this. Thoughts? [/QUOTE]
