Mail.ReadWrite

Allows the app to create, read, update, and delete email in user mailboxes. Does not include permission to send mail.

Administrators can configure application access policy to limit app access to specific mailboxes and not to all the mailboxes in the organization, even if the app has been granted the Mail.ReadWrite application permission.

Mail.ReadWrite is valid valid for both Microsoft accounts and work or school accounts.

Merill's Note

For an app to access data in Microsoft Graph, the user or administrator must grant it the permissions it needs. This article lists all the Microsoft Graph APIs and your tenant data that can be accessed by the application (vendor/developer) if you consent to the Mail.ReadWrite permission.

If you need to create an audit report of the permissions granted to all the apps in your tenant, you can run the Export-MsIdAppConsentGrantReport command. See How To: Run a quick OAuth app audit of your tenant
