I have these settings in my COS - Preferences - Receiving Mail
>Polling Interval: 15 minutes
>Minimum mail polling interval: 2 minutes
>Out of office cache lifetime: 7 days
Users report that they have to click on the Get Mail button to get new messages; Zimbra doesn't automatic check/download new mails after 15 minutes as specified in the polling interval setting. What am I doing wrong or users have to click on the Get Mail to see their new messages?
