Hi,

Maybe you should enable detailed logging for pop3 service (in troubleshooting options) and then check in the logs if you have some interresting errors that could help you resolve the issue.

At the moment on 7125 we don't have (yet?) complaints from people using pop3 (but it's only like 3% of the users).

Kind regards

So I have detailed logging on it.  But its just shows users logging in.  And the users that are having trouble are not being shown logging in.

Strange,
How are the outlook clients configured to access pop3 ? Port 110 or 995 ?

Can you remote one of the computer and try to connect to your server ports with for example a "PuTTY" client?

Maybe it's a network problem, or some port binding problem on SmarterMail.

Hi Chase. You may want to check to see if your ports are still bound correctly in SM and that all of your SM services are running after the upgrade. Every time I do a SM upgrade it stops all of the services for some reason. Log into your SM admin interface and go to Troubleshooting > Services. Be sure they are all started. I hope this helps.
