On macOS Mojave 10.14.1, this is what I found:
Microsoft Auto Update had 19 files on macOS in multiple directories, after I'd already removed it from ~/Library/Containers. You should remove those folders to completely remove the application and all it's traces. Some of the directories have spaces in their names, make sure to type those spaces with a leading backslash, if you use rm -Rf to remove those!
In your System Library:
/Library/Application Support/Microsoft/MAU2.0/Microsoft
AutoUpdate.appIn your User-Library:
~/Library/Preferences/com.microsoft.autoupdate2.plist
~/Library/Preferences/com.microsoft.autoupdate.fba.plist
~/Library/Application Support/Microsoft AU Daemon
~/Library/Saved Application State/com.microsoft.autoupdate2.savedState
You will also find temporary files, I had them in four different locations, but your mac will clean those up eventually. I found some in the system- and user-caches, as well as in /private/var/folders, if you really want all traces gone, you'll have to track those down as well.
