Using older versions of Outlook for Mac in business environments
I had the same issue w/ trying the script, but another forum thread has an easier method:

Since I've done this the problem hasn't reoccurred, but I've had long periods of stability before, so we'll see how this goes...
Over two weeks since I made the change and I haven't had the issue pop up since (*knocks wood*). Granted, since then it's also been updated to 15.8 w/ the Office 365 preview but I'm gonna say I'm cured...at least until MS finds a new way to break it :)
