This FAQ was last modified on: Thursday, March 2, 2017 02:08pm


When you use Instant Search in Microsoft Outlook 2013 and Microsoft Outlook 2016, you receive the following message:

"No matches found".

Or, only some of the expected results may be returned. If you view the Indexing Status dialog in Outlook, you may see the following message:

Search results may be incomplete because items are still being indexed.

This occurs even if you include search criteria for items that do match

Follow these steps to verify that indexing is complete:

  1. In Outlook, click in the Search box.
  2. Click the Search tab, click Search Tools, and then click Indexing Status.
  3. When the Indexing Status dialog appears, you should see the following:

    Outlook has finished indexing all of your items.
    0 items remaining to be indexed.

Search Feature - Performance Issues

  • We've noticed that the Search feature functionality in Office 365 begins to degrade once a user's Inbox is near or past 100,000+ items. A workaround to this issue is clean out your Inbox by moving emails to folders or moving them to Archive or .pst files or creating rules to move emails within a select range to other folders. This method has proven to  help increase performance with the Search feature in Office 365.
