Ask the Experts: Basic Authentication Deprecation in Exchange Online (Repeat)

Come meet some of the team responsible for deprecating Basic Auth in Exchange Online.

Speaker: Greg Taylor

[astonish]

With the basic auth being depreciated;
One of our vendors have reached out requesting that we need to make the changes in our Azure environment, to grant them office 365 exchange online api app permission. This external vendor app only applies to one of our custom domain.

My concern is I do not want to give access to all other custom domains in my organization to this external vendor app. And if I do grant the external vendor app access to the org wide, how much of our org environment will be exposed to the vendor, what kind of access will they have etc.

Is it possible to enable and grant my office 365 exchange online api permissions to an external vendor app specifically to one of my custom domains?... Just wondering also, if this can be done by specifying a security dynamic azure group and add members?

Any suggestions and how would very much appreciated.

Many thanks
