How to Rebuild/Reset Outlook Search Index? Check Outlook index status as shown above and try to search for something. Give Outlook some time to complete the full indexing (it depends on the number and size of mailboxes and connected PST files). Check Microsoft Outlook in the indexing options and save the changes. Now you need to enable Outlook Indexing in Search Settings, which was previously disabled. Open an elevated PowerShell console and restart the WSearch service: Check the box Allow this file to have context indexed in addition to file properties -> click OK.Right-click the OST or PST file you need and select its properties.Select files one by one and click Open file location.


The Outlook search index is rebuilt when you add a new mailbox or Outlook Personal Folder (PST) file, move emails between folders, etc. Outlook is currently indexing your items.
