ApplicationImpersonation

Question

I do have an Azure app(use for office365 mailbox access) and use EWS mailbox operations.

How can I grant relevant permission(ApplicationImpersonation) by using Graph API?

Answer 1

Hi @Gary Semple

Select the endpoint that grants permissions based on the flow being used.

When using auth code flow, authorize interactive logins through /authorize endpoints.

When using the client credential flow, authorization is done through the /adminconsent endpoint, which requires an administrator to authorize.

Or you can grant permissions directly to the application service principal through this documentation tutorial

Hope this helps.
