If an Office application, such as Word or Outlook, isn't working correctly, sometimes restarting it will fix the problem. If that doesn't work, you can try repairing it. When you're done, you might need to restart your computer.
-
Right-click the Start button, and select Apps and Features on the pop-menu.
-
Select the Microsoft Office product you want to repair, and select Modify.
-
Note: If you have a standalone application, such as Word or Outlook, search for the application name instead of searching for the suite name like Microsoft 365 Family or Office Home and Student.
-
Choose one of these options based on what's presented:
-
In the window How would you like to repair your Office Programs, select Online Repair > Repair to make sure everything gets fixed. (The faster Quick Repair option is also available, but it only detects and then replaces corrupted files.)
-
In Change your installation, select Repair and then select Continue.
