Microsoft Office 365
If Outlook, Word, or any other Microsoft Office program isn't working correctly, one of the first solutions you can try is an Office Repair.
Step 1: Click on Start and then Control Panel.
Step 2: After the Control Panel window opens, click on Uninstall a Program.
Step 3: A list of all installed programs should now appear. Highlight Microsoft Office 2016, and click on Change.
Step 4: After the dialog box loads, choose the Repair option and click Continue.
Step 5: This process may take a few minutes, but after completion, you will be prompted to exit and restart any open Office programs. You may then click Close. You may be prompted to reboot your computer to apply all changes and complete setup.
