1.       Did you make any changes to the computer before the issue occurred?

2.       Does the issue occur only while searching in outlook?


I would suggest you to follow the steps provided below and check if it helps:


Method 1: If you're having problems locating specific files, folders, or other items on your computer, try using the Search and Indexing troubleshooter to fix the problem.



Method 2: If the above does not work, then I would suggest you to rebuild the search index.

To rebuild the index:

a. Open Indexing and Search Options by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking Indexing Options.

b. Click Advanced, click the Index Settings tab, and then click Rebuild. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

Refer the link below for more details:

Method 3: Also try to run [System File Checker] SFC scan on the computer which would scan for corrupt system files on the computer and replace them.
