Outlook does not return search results

Symptoms

When you search in Microsoft Outlook, no search results are returned.

Cause

This issue occurs because the Windows registry contains search-related data that is invalid. This causes Outlook data not to be indexed.

Resolution

Important
Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.

To resolve this issue, rename the registry key that contains the invalid search-related data. This disables the key. Then, create an Outlook profile. To do this, follow these steps.
Step 1: Rename the registry key to disable it
  1. Exit Outlook.
  2. Click Start, type regedit.exe in the search box, and then press Enter.
  3. Locate and then click the following subkey in the registry:

    HKEY_CLASSES_ROOT\CLSID\{9E175BAF-F52A-11D8-B9A5-505054503030}
  4. On the Edit menu, click Rename.
  5. Change the name of the subkey to the following:

    {9E175BAF-F52A-11D8-B9A5-505054503030}.bak
  6. Exit Registry Editor.
Step 2: Create a new Outlook profile
  1. In Control Panel, click Mail, and then click Show Profiles.
  2. On the General tab in the Mail dialog box, click Add.
  3. In the New Profile dialog box, type a new profile name, and then click OK.
  4. In the Add New Account dialog box, type your email account information, and then click Next.
  5. After your account is successfully configured, click Finish.
  6. Click Always use this profile, select the new profile, and then click OK.
  7. Start Outlook.
  8. Wait for the new Outlook profile to fully sync and index the items from the user's mailbox. This may take several hours, depending on the size of the mailbox.

More Information

This issue can occur when you run a 32-bit instance of Outlook on a computer that is running a 64-bit version of Windows. The 64-bit Search Protocol Handler is registered. However, because Outlook is 32-bit, the 32-bit Search Protocol Handler is required. The Search Protocol Handler cannot start MAPI because it is located in the 64-bit native hive of the registry instead of in the WOW6432Node subkey only. In this situation, Outlook data is not indexed.

When this issue occurs, an entry that resembles the following is logged in the Application log:

Log Name: Application Source: Microsoft-Windows-Search Event ID: 3036 Task Category: Gatherer Level: Warning Description: The content source <mapi://{S-1-5-21-1123561945-1708537768-1801674531-4211123}/> cannot be accessed
