Microsoft grants read and manage access to your entire mailbox. Junk Desk uses it to list junk mail and move only messages you select. It cannot send mail.

Your messages and sign-in tokens pass directly between this browser and Microsoft. Junk Desk has no server that stores your mail. Disconnect clears this app’s browser session; revoke access in your Microsoft account at any time.

Moves can be undone until Microsoft’s retention period expires. Moving mail to Inbox doesn’t add a safe sender.
