Question details

Users need to resolve an issue where Outlook 365 locks up and becomes unresponsive when attempting to search for emails.

Product: Microsoft Outlook 365
Device & OS: Windows
Scenario: Searching for specific emails or contacts within the Outlook 365 desktop application.
Observed behavior: Outlook 365 freezes during search. Concurrently, the Windows Event Viewer reports VersionOverrides parsing errors for Suggested Meetings, and SearchApp.exe stops interacting with Windows.

Before you start

Verify if the freezing occurs during every search or only specific queries, and note the exact time of the freeze so your IT administrator can correlate it with Event Viewer logs.

Solution 1Recommended

Open a Service Request with Microsoft 365 Technical Support

This solution is highly recommended for Office 365 Global Administrators who need advanced diagnostics for tenant logs.

Because this issue involves complex interactions between SearchApp.exe and the Windows search components, standard troubleshooting steps may not apply. Advanced tenant and system logs must be inspected by Microsoft directly to resolve the freezing issue.

Access the Admin Center

Navigate to Support

Click on the 'Support' or 'Help & support' option located in the left-hand navigation menu.

Create a New Request

Open a new service request detailing the Outlook 365 search freeze, and mention the VersionOverrides parsing errors and SearchApp.exe crashes found in the Event Viewer.

Solution 2

Contact Your Organization's IT Administrator

This step is required for standard end users experiencing the Outlook search freezing issue, as they lack tenant-level access.
