But the ‘getting there’ part might be the hard part, and that’s what this blog post is about. Modern Authentication, based on OAuth2, has a lot of advantages and benefits as we have covered before, and we’ve yet to meet a customer who doesn’t think it is a good thing. Since we announced in 2019 that we would be retiring Basic Authentication for legacy protocols we have been encouraging our customers to switch to Modern Authentication. I wanted to pass this Exchange Team Blog article along since it has come out with updates recently. I worked with doing some OAuth calls when I was in EXO CSS at Microsoft.

This type of authentication has been around since about 2017 timeframe with OAuth v1 and now has updated with OAuth2.
