How to prevent Grammarly for Microsoft Office from updating automatically

Important: Grammarly for Microsoft Office will no longer be updated. We suggest switching to Grammarly for Windows (if you use Windows 10 or newer) or Grammarly for Mac (if you use macOS 10.14 or newer), which supports integration with multiple applications and websites, including Microsoft Office apps. 

If you’d still like to prevent Grammarly for Microsoft Office from updating automatically, you need to block the domain “” in your Windows Firewall. To do that, follow these steps: 

  1. Click the Windows button and start typing Notepad. Then, right-click Notepad and choose Run as administrator
  2. In Notepad, click File > Open. In the address bar, paste or type this text:


  3. Select All files in the Type of file section: prevent_automatic_update.png
  4. Double-click hosts
  5. In the file, type

    Note: You need to press Tab twice after typing

  6. Exit the Notepad and click Save to save the changes
