Email - Check for new Messages, Does not work!

Email - Check for new Messages, Does not work!

Is there anything that can be done about this?

Check for new Messages every  minutes
Maximum number of emails per cycle  (should be between 20 to 200.)

I am not sure if this feature ever worked in Zoho, it seems like we have been manually refreshing to get new emails for as long as we have been using Zoho ( 5 Years ).

Any tips on how to improve this.  I had it set to 3 minutes and that never worked.

Thanks
Steve
