How to Rebuild the Search index in Microsoft Outlook

If Outlook is not searching all of your email correctly, you can rebuild the Outlook search index to fix this:
  1. Click on File then Options
  2. Select Search on the left then click Indexing Options


Click Advanced


Click the Rebuild button


This will cause Outlook to rebuild its entire search index. This can take a long time to complete. Some people can use outlook while performing this task, but we recommend to do this at the end of the day.
