Why does the Office flickering issue happen?

Outlook 365 flickering and flashing
There are four reported ways to fix the Outlook 365 flickering and flashing issue:
- Disable all unnecessary Outlook add-ins.
- Change Outlook Display Settings
- Update Graphics Driver
- Repair Office
These solutions require that you have updated Microsoft Edge to the latest version and have an admin account.
Disable all unnecessary Outlook add-ins
If you’re experiencing problems with Outlook, it’s possible that a third-party add-in or extension is to blame. These programs can enhance your experience, but if something goes wrong after updating or installing one of them, it could cause an issue.
- Open Outlook and wait for the sync to complete
- Then go to File > Options > Add-ins.
- Disable all of them, and restart Outlook.
- If this works, you will need to enable them individually and determine if the issue is resolved.
Another way to check for Outlook problems is to open it in Safe mode. In Safe mode, add-ons will not load and Outlook functions will be limited. Try using Outlook for some time and see if the problem persists.
Change Outlook Display Settings
You can disable the high-performance Outlook setting from the Graphics section in Windows. Windows usually decide which mode to use, but you can also set it to choose Power saving mode or let Windows decide. Since Hardware acceleration is not part of Outlook anymore, you can set this.
Settings>Display, Graphics. Select the Office app, and then click on the “Options” button. Then select “Power saving,” and save the change. If you can’t find the Office app, you can add it. First, click on the drop-down for Add an app, choose Microsoft Apps, then click on Browser. This will display the list of available apps on the PC.
One of the best ways to fix flickering in Microsoft Office is to repair the program. If the issue is limited to Outlook Office and not happening elsewhere, it might be because of a corrupt file.
- Open Windows Settings (Win + I)
- Navigate to Apps > Apps & features > Office
- Click on the Repair button to start repairing Office installation.
There is another way to repair Office; by using the old Control panel. To do this, navigate to Control Panel > Programs > Uninstall or Change. Select Microsoft Office and then click on the Change button. You will be given the option to repair it right away. There are two options available when using this method; Quick Repair and Online Repair. The latter will take more time but will do a much better job.
If this doesn’t work, you can try uninstalling and then reinstalling the program. This process will ensure that all files are fresh and free of corruption.
