MFA support for Mac Mail


In order to use Mac Mail with MFA, you will need to upgrade to Mac OS X Mojave.

While performing an upgrade is straight-forward, you may want assistance from local support before proceeding. If you do not wish to upgrade at this time, the recommended application, Microsoft Outlook for Mac works with older versions of macOS.


Upgrade to Mac OS X 10.14 Mojave


If your Mac supports Mac OS X 10.14 Mojave, you can upgrade Mac OS X. The following Macs can upgrade to Mojave:

MacBook models introduced in early 2015 or later
MacBook Air models introduced in mid 2012 or later
MacBook Pro models introduced in mid 2012 or later
Mac mini models introduced in late 2012 or later
iMac models introduced in late 2012 or later
iMac Pro (all models)
Mac Pro models introduced in late 2013, plus mid 2010 or mid 2012 models with recommended Metal-capable graphics processor, including MSI Gaming Radeon RX 560 and Sapphire Radeon PULSE RX 580

Check to see if you have enough space

You should ensure that your hard drive has at least 20GB free before starting the upgrade process

  1. Open the App Store and search for "macOS Mojave"
  2. Click Download
  3. The installer should open automatically. Click "Continue" and follow the onscreen instructions to begin the upgrade

Mac/Apple Calendar

Unconfirmed, but it seems likely that the Mac/Apple Calendar application on macOS also needs to updated to Mojave (10.14.x) to support MFA.

Mac OS X 10.13 and older

If you cannot or do not wish to upgrade to Mac OS X 10.14, you will be unable to use Mac Mail with MFA. Please consider installing Microsoft Office 365 and using Outlook, or you can use Outlook Web Access by going to
