Microsoft 365 Email (Outlook) Error

Unable to connect Outlook business account to Make. When I go to get authorization, it shows up as the “Integromat” app and provides this error message. Any advice on how to resolve? Thanks!

So I haven’t had a chance to verify this yet.

But my experience with outlook (post the horrible reputation hotmail days)
is that its one of the most finicky platforms to setup right across the board in relation to email.

have you tried going the developer route to integrate, by generating API keys. and using the advanced settings for the new Microsoft connection.
and in the azure dashboard setting make as the redirect URL.
