New to this forum, not so new to Zimbra.
Overall it does just fine, but in a corp environment I have several client pc's that just do not get their email without having to click the Get Mail button.

On mine, new email is just there and shows up while my Zimbra is open. My timing is set to the default 5 min and so are others who just don't get any new email without clicking Get Mail.

Two accounts listed; Primary says Zimbra, another account called Google says POP. It's the same even for the "non-working" get mail PC's.

Any suggestions where I can check/look?

Thanks very much.
