I started off using a ZCS server with the webmail interface. I manually get email from a couple my POP accounts, by selecting the folder from the POP account I want, and then clicking on "Get Mail".

This works ok. Then I tried out Zimbra Desktop with my ZCS account. I successfully synced ok, and everything seemed fine.

When I want to receive email on the Zimbra Desktop, I click "Send/Receive". However it only gets email from ZCS that has already been manually downloaded into ZCS (with the web interface). What it should do (I think) is cause ZCS to get the new email via POP automatically, (and transfer it to Zimbra Desktop).

Can anyone suggest a solution?
