Search is slow or not working properly in Microsoft Outlook


Do you experience this problem when searching in Microsoft Outlook:

  • It can take a very long time to finish searching
  • Searches display incomplete results, the items you are searching for do not display

I have seen this occurring regularly at clients running Windows 7 and Windows 10, as well as different versions of Microsoft Office (2010, 2013 and 2016). Sometimes it occurs after Windows has done updates and sometimes it just starts misbehaving randomly.

I have found that rebuilding the search indexes seems to solve it MOST of the time.

You do this as follows:

Open Control Panel and Indexing Options.


Now click on the Advanced button


and click Rebuild


Click OK on the Rebuild Index dialog box


Note that it may take a few hours – so leave your device on and running with Outlook open. If you do a search before the indexing is complete, your results will be incomplete.
