Confused about using Outlook, Mail (POP)

Confused about using Outlook, Mail (POP)

We set up ZOHO business account and I followed the directions for changing the MX, setting up users and emails, etc.

It was just a few hours ago, so mail isn't coming in yet, BUT...

most, if not all, our users would like to get and receive mail through their email clients (Outlook, Mail/Mac) and not the web interface.

Is this not possible?

If so, how? I can't find how to set up the accounts in our clients in any help document.

If not, we'll have to move. I misunderstood reading when we set this up.
