Outlook Mac 365 Update Keeps Crashing on Startup

Copper Contributor

Hey All,


I've kept putting off selecting the button to use the new Outlook update due to problems in the past. I finally decided to give it a go as asks every time the app is opened.


As soon as it loads it starts connecting the email accounts via imap and then crashes showing the attached warnings/errors.


What is this and how do I fix? 


It literally will not stay open long enough to try band switchback or anything.


Obviously, now wishing I never took the risk.


Thanks, Jaye
