If you've connected your Outlook account to Hasleo Backup Suite for email backup notifications but no longer need this feature—or you want to tighten your Microsoft account security—simply disabling the feature inside the software is not enough. The OAuth 2.0 authorization token stored on both Microsoft's servers and your local machine must be removed separately to fully sever the connection. This guide provides a complete walkthrough covering both steps: revoking application permissions in your Microsoft account settings and deleting the locally cached authentication token file.

Why revoke access permissions?

If you no longer want Hasleo Backup Suite to access your Outlook account (e.g., used to send backup notifications), you should revoke its permissions. This prevents the software from reading or sending emails on your behalf. This tutorial shows you how to completely remove access in two steps: revoking permissions via Microsoft's consent management page, and deleting locally stored authentication tokens.

Step 1: Revoke the access permissions that Outlook has granted to Hasleo Backup Suite.

Step 1. Visit https://account.live.com/consent/Manage, sign in with your Microsoft account, and you will see a list of all authorized applications.

Step 2. Locate Hasleo Backup Suite and click "Edit" below it.

Step 3. The permissions you have granted to Hasleo Backup Suite are listed here. Click "Remove these permissions" below to revoke them.

Step 4. Once you have successfully revoked the permissions for Hasleo Backup Suite, it will disappear from the list of apps.

Step 2: Remove the token stored by Hasleo Backup Suite that is used to access Outlook.

Step 1. In the address bar of File Explorer, directly type %ProgramData%\Hasleo Backup Suite\Email Auth2 to open the folder where the tokens are saved.

Step 2. Locate the file whose name starts with outlook_, followed by your email address, and ends with the .bin extension, then delete that file.
