Do you need to restart your computer after the repair process is complete? In the Category view, under Programs, select Uninstall a program. Microsoft Support and Recovery Assistant is a great tool to help you troubleshoot Office, Microsoft 365, or Outlook issues. If it can't fix the problem, it will suggest the next steps and help you contact Microsoft support. To begin the process, open Programs and Features in Control Panel.
In Windows 10, you can get there by opening the hidden shortcut menu. When you run a quick repair operation, Office will attempt to perform simple repairs with local files that are already on your computer. When the repair is finished, start Outlook with the profile associated with the Outlook data file you just repaired. Usually, you have to try the quick repair first, and if your problem is not fixed, use the Online Repair option.
