Outlook 2003 hangs during send/receive (POP3/SMTP)

Posted on 2006-04-25

Office 2003 Std SP2, Win XP Pro Sp2, Windows Server 2003 SP1, Outlook is set up for pop3/smtp, McAfee VirusScan Enterprise 8.0i, Sonicwall TZ-170 firewall with email scan, TCP/IP LAN.

We have 56 email accounts through a third part email provider (not our ISP).  We have used Office 2003 for about 1 year now.  In the past few weeks 4 of these accounts started hanging up when Outlook sends/receives email.  Have to use task manager to close outlook.  I have searched the Microsoft newsgroups and found that many users are complaining about the same issue, but I did not find a solution.  I even opened a tech support case with Microsoft.  They don't have a solution either.  To rule out email antivirus email scanning as the issue, I disabled email scan on one machine and removed McAfee from another problem machine.  The problem was not resolved so McAfee does not appear to be the issue.  Does anyone know of a solution for this issue?

    Greetings, usemco1 !

    1. Register an important send/receive library file.  Go to Start > Run and type regsvr32 inetcomm.dll

    2. Check if antivirus email check is slowing sending and receiving.  Disable it.

    3. In the account settings, Advanced settings, change the server timeout time from 1 min to 5 min

    4. Check if outgoing mail server authentication is required. Select that option in account settings and use same settings as incoming server

    5. Your ISP may be blocking port 25. Try using alternate port 587.

    6.  Check with email provider Tech Support to determine if server is having trouble.

    7. See this troubleshooter for not sending

    Best wishes!
