The “Operation Failed” error in Microsoft Outlook can be a significant disruption in your daily work routine, preventing you from sending emails, accessing calendar events, or even opening the application. This error can be caused by various issues ranging from incorrect account settings to corrupted Outlook profiles. In this article, we’ll walk through the top 7 fixes to help you resolve this error and get Outlook running smoothly again.

1. Check for Outlook Updates

Outlook, like any other application, needs to be up-to-date to function correctly. To check for updates:

– Open Outlook and click on “File.”

– Choose “Office Account” and then “Update Options.”

– Click on “Update Now.”

If there are any pending updates, allow them to install and then restart Outlook.

2. Disable Add-ins

Add-ins can enhance functionality but might also conflict with Outlook. Disable them by following these steps:

– Open Outlook in Safe Mode by typing `outlook.exe /safe` in the Run dialog (Win + R).

– If Outlook opens without the error, go to “File” > “Options” > “Add-ins.”

– At the bottom of the window, choose “Manage: COM Add-ins” and click “Go.”

– Clear all the checkboxes to disable all add-ins, then restart Outlook normally.

3. Repair Office Installation

A repair of Microsoft Office can fix issues with Outlook:

– Find your Office installation and select it.

5. Check Your Account Settings
