Á við um: Outlook 2016Outlook 2013Microsoft Outlook 2010


When you use Instant Search in Microsoft Office Outlook, you receive the following message:
No matches found.

This occurs even if you include search criteria for items that do match items in your mailbox and Windows Desktop Search (WDS) is configured to index the Outlook Data (.pst) file or Offline Outlook Data (.ost) file.

Additionally, if you view the Indexing Status dialog in Outlook, you receive one of the following messages:
0 items indexed.

Outlook is currently indexing your items.
# items remaining to be indexed.

Note The number of items remaining to be indexed represented by the # placeholder in this message never decreases.

Note This same message is shown if you open Indexing Options in Windows Control Panel.


The Allow service to interact with desktop option is enabled for the Windows Search service.


To resolve this issue, disable the Allow service to interact with desktop option on the Windows Search service. To do this, follow these steps:

  1. Exit Outlook.

    Note Also exit Microsoft Lync or Communicator if it is running.
  2. Run services.msc.
  3. Right-click the Windows Search service, and then click Properties.
  4. Click Stop and wait for the service to stop.
  5. Click the Log On tab.
  6. Click to clear the Allow service to interact with desktop option.
  7. Click Apply.
  8. Click the General tab.
  9. Click Start and wait for the service to start.
  10. Click OK.
  11. Start Outlook.
