How do I resolve time out issue on Outlook?

I have an Exch 2007 server and clients use Outlook 2007. Some accounts were no longer download messages via POP, but access via OWA is ok! Returns message timeout and no mail is downloaded. Any ideas?

Hi, firstly make sure the service is running , go to services.msc and ensure the pop3 service is running, if this is not it effects all users.

Make sure the user account is enabled for pop3


Check the timeout settings


Are the users with the timeout issues remotely connected , or on the same LAN as your Exchange server or is it hosted.

You can test pop3 connectivity using telnet.

The accounts are enabled for pop3 (are old accounts) and all are remotely connecteds and in the same LAN there other users that connect with no problems with pop3 protocol.
If it was me I would connect to one of the remote systems for troubleshooting. You can use tools like teamviewer , logmein rescue or Goto Assist for this, you may have your own already. When connected I would open a Telnet window and follow the article I listed above just to make sure I get a POP3 connection.

This is as simple as typing:

telnet> open exim.mydomain.com 110
Trying x.0.241.27...
Connected to exim.mydomain.com.
Escape character is '^]'.
+OK Hello there.

This connection was instant...

You can try and increase the timeouts if it does connect, but slowly.

Does the issue move amongst your users or by time of day , for example, sometimes a user can POP their mail but at other times they cannot and its always ok in the evening or in the morning but during the working day its very intermittent etc. I would also want to look at the router logs, in real time, so you can see the traffic on the Internet connection then see incoming POP3 connections (TCP:110 or TCP:995) to help determine if its a saturated internet connection. I am not sure how many mailboxes or remote users you have.

Also, and this is not a suggestion for a solution, but Outlook Anywhere is excellent. It is so much better than legacy POP3 and even if your users run Mac they can use Mac Mail or Outlook 2011 (even Entourage 2008) and if you have Linux Desktops like Ubuntu there are also opensource solutions that give you access to much better messaging protocols.
