To resolve this issue, please restart Microsoft Word or Outlook. If this doesn’t help, we recommend that you reinstall your video card driver:
- Go to Display settings > Advanced display settings > Display adapter properties > Properties > Driver and click Uninstall Device
- Restart your PC, go to Display settings > Advanced display settings > Display adapter properties > Properties > Driver and click Update driver
If the issue persists, please press Win + R, insert %Temp% and press Enter. Then, delete all files in the Temp folder that opens next. Also, make sure there is at least 1 GB of free space on your C drive.
If Grammarly for Microsoft Office doesn’t work after trying these steps, and you’re using Windows 10 or newer, we suggest switching to Grammarly for Windows. This product offering also supports integration with Microsoft Word and Outlook. To find out more, check out this article.
