I'm using Outlook for Mac 2016 version 16.12 on Mac OS Sierra 10.12.6 with a Microsoft Exchange mailbox. I'd like to send an e-mail in the future, but schedule it today. I understand that this feature is called "delay delivery." However, it appears that Microsoft has only enabled this feature for Outlook users with an Office 365 mailbox.
Question: How do I delay delivery of an e-mail, using Outlook for Mac 2016, with a Microsoft Exchange mailbox?
