How to Remove Microsoft Access to Google Account?

Is Microsoft connected to your Gmail account by either linking Outlook to Gmail or signing in to Microsoft using Google? Do you want to remove Microsoft access to your Google Account? Then, this blog will help you. Here, I will provide a step-by-step process to unlink your Microsoft account from your Google account with important tips and tricks.

Usually, organizations or businesses connect their Microsoft account to Google Workspace for collaboration and file management. However, if you find Microsoft listed under “Third-party apps with account access” in your Google account, it means you previously granted permission. This does not necessarily mean your account has been hacked. In reality, it points out that you allowed Microsoft service to access certain Google data. If you don’t know how this happened, below are the possible reasons.

Why does Microsoft have Access to your Google Account?

• Microsoft services like Outlook, Microsoft 365, or Teams allow you to sign in with Google. When you choose this option, Google shares your credentials, which results in Microsoft appearing in your Google account’s third-party app permissions list.
• You added your Gmail account to Outlook and granted the permissions to read and send email, access contacts, and sync calendar events. This creates a connection between Outlook and your Gmail mailbox.
• If 2-Step Verification is enabled in Google, you generate an app password in Gmail for login to your Microsoft account. With this password, the Microsoft apps have access to your Google account.
• Google uses OAuth 2.0 authorization to grant Microsoft access. This allows you to access specific Google data in Microsoft.

So, is this access a security risk? No, not entirely. If you intentionally connected Outlook or Microsoft 365, there is no issue. But you should remove and review the permission if you no longer use the Microsoft app, switch your platform, suspect unauthorized activity, or want to improve account security.

• Check Google security. In the Google account, go to the Security section. Then, run Security Checkup to review recent activity, connected devices, etc.
