Run an Online Repair for Microsoft Office

Use this solution if the search function works perfectly on the web version of Outlook, indicating that your local desktop application is corrupted or missing essential files.

Microsoft Office includes a built-in repair tool that can fix most software bugs, missing files, and corrupted installation components. An Online Repair is more comprehensive than a Quick Repair as it re-downloads missing files.

Close all Office applications

Ensure that Outlook, Word, Excel, and any other Microsoft Office applications are completely closed before starting the repair process.

2
Open Control Panel

Click the Windows Start menu, type 'Control Panel' in the search bar, and hit Enter to open it. Ensure your view is set to 'Category'.

3
Access Programs and Features

Click on 'Uninstall a program' under the Programs section to view a list of all installed software.

4
Initiate the repair tool

Scroll down to find 'Microsoft 365' or 'Microsoft Office'. Right-click it and select 'Change'. If prompted by User Account Control, click 'Yes'.

5
Run Online Repair

Select the 'Online Repair' option and click 'Repair'. Wait for the process to complete, then restart your computer and test the Outlook search.

Frequently Asked Questions

Why does Outlook display the 'Your request can't be completed' error?

This error is typically triggered by corrupted Outlook Personal Storage Table (PST) or Offline Storage Table (OST) data files, a malfunctioning Windows Search service, outdated software, or conflicting third-party add-ins.

Will creating a new Outlook profile delete my old emails?

No. Creating a new Outlook profile simply creates a new local configuration to access your emails. As long as your emails are stored on the server (Exchange, IMAP, or Outlook.com), they will sync directly to the new profile.

Does running an Online Repair remove my personalized settings?

An Online Repair will reinstall the Office suite components, which may reset some application preferences to their default states. However, your emails, documents, and fundamental account settings will remain intact.

How can I fix the Windows Search service if it is causing the issue?

You can restart the Windows Search service by pressing Windows Key + R, typing 'services.msc', locating 'Windows Search' in the list, right-clicking it, and selecting 'Restart'. You should also ensure its Startup type is set to 'Automatic'.
