Microsoft Graph Me

Microsoft Graph Me is a shortcut to the signed-in users resource, letting apps work with the current users data across Microsoft 365 without knowing their user ID. Through the /me endpoint, you can retrieve and update profile details and settings; get the users photo and presence; read, send, and organize mail; manage calendar events and contacts; access OneDrive files; interact with Teams chats and joined teams; view manager, direct reports, and group memberships; and work with To Do and Planner tasks. All operations are governed by OAuth permissions and tenant policies, so apps only see or change what the user or admin has consented to.
