Outlook 365 suddenly won't open
Hello; Outlook worked this morning, now it won't open, says to open in Safe Mode, but that doesn't work, tries to open for 5 seconds than nothing. Restarted PC and no help. Please advise! Steven F 60...

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...
