You can't open the application "Microsoft Outlook.app" because it is not supported on this type of Mac

Today all of a sudden Outlook crashed on my MacBook Pro. When I try to restart it, I got "You can't open the application "Microsoft Outlook.app" because it is not supported on this type of Mac" pop up.

Rather disturbing I thought. Immediately, I started to ask around if anyone has encountered this same problem before. No luck.

Great, I thought. Time to ask Uncle Goog.

Fortunately, I found this link.  Particularly the part that said:

Update using the Microsoft Autoupdater (MAU):

• Open any Office application and select "Check for Updates" under Help in the Menu bar. Once MAU is launched, select "Keep in Dock"
• Log out/in as described above.
• Select the MAU in the Dock and download the updater.
• After it downloads, quit the MAU then install.
• RESTART

In my case it's a bit simpler:

• Open any Office application and select "Check for Updates" under Help in the Menu bar.
• Once MAU is launched, click "Check fir updates"
• In my case, I happen to find updates I can apply to Office. Follow the instructions to apply the updates.
• My Outlook icon on the Dock which previously doesn't look healthy, now looks good again. I clicked it and it works as expected.

Your mileage may vary.
