Microsoft Office 365 for Mac Hung Updates

Last week I started having a problem with Microsoft Office 365 for Mac crashing when I tried to open one of its apps. I kept getting a message indicating that Outlook (or whatever) would open when an update completed. The app never did.

What was happening was that the Microsoft Office AutoUpdate app kept hanging. Here's what I had to do to fix it:

1. Close any Office app that happened to be still open.
2. Kill Microsoft AutoUpdate. You can do this with Activity Monitor or like I did, via the terminal.
1. Open Terminal.app
2. Do ps ax | grep Auto to find the PID
3. Do sudo kill -9 <PID>
3. Download the latest Microsoft AutoUpdate from here and ran it.
