I've used this thread https://www.reddit.com/r/sysadmin/comments/hrq0mn/outlook_immediately_crashing_on_open_after/fy5nnx2/ and been able to fix all the machines I've come across this morning. According to the Service Health Page they have located the problem and are suppose to be rolling a patch out to fix it.

You're basically downgrading to an Office insider build from 2016. Please make sure to check your office version after you did that. I don't want to know how many people will have 1. rolled back to a dinosaur version with a lot of features missing and 2. completely have messed up their O365 UpdateChannel registry settings, just by blindly copy pasting something from Reddit...
