What does the password prompt look like? If you are getting the old Basic auth one, you need to make sure that Modern auth is enabled *both* on the server- and client-side. <br />

for outlook 2016 / O365 thick client, you don't need any reg entries, by default they support modern auth<br />
enable it from server end (Exchange Online shell to be used)

They do support it by default, but it might be disabled by GPO, so make sure you double-check things. And you didnt answer my question on how the prompt looks like?

you don’t need any registry hacking. it is just an authentication issue caused by server side due to untrusted sign-in. depening on your Outlook version, removing profile or re-logging in via web will fix it.
