MacOS – How to refresh / check new mail in Mail

How do I refresh / check new mail in Mail?

By default, I don't see a toolbar button to do so in Mail 5.1 on Lion.

Best Answer

Apple Mail's check for mail icon looks like a new mail message icon, and can be found here:

Apple Check Mail ICon

If it can't be found you can add by right-clicking on the toolbar and choosing customize:

Customize Toolbar

You can then select the icon from the list and drag it to the toolbar at the top:

Check Mail Icon

You can also use "Mailbox" -> "Get All New Mail" which has a shortcut + + N.

You don't need to synchronize. Synchronize does more than a new mail check (see this answer)
