Microsoft Graph API with OAuth2

We provide two options for Graph API connections.

Delegated access (https://docs.meta-inf.hu/email-this-issue/~/revisions/mYKQuRriMlSJeyH2TzSD/administration/mail-server-connections/microsoft-with-oauth2/microsoft-graph-api-with-oauth2/graph-api-with-auth-code-delegated-access)

• A user is signed in.

• The app reads, writes, or sends as that user.

• The app can only do what the user is allowed to do.

Application access

• No user is signed in.

• The app reads, writes, or sends from a mailbox on its own.

• Requires admin consent because it can access mail without a user.
