Shared Mailbox: Problems with search results

If you're not getting expected results from a shared mailbox search or you receive an error, follow one of these steps:

Disable server search as a short-term solution. To do this, follow these steps:

Important: The following steps show you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Please make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, go to How to back up and restore the registry in Windows.

  1. In Windows, right-click Start, and then select Run. In the Open: box type regedit, and then click OK. This will open the registry editor.

  2. In the registry editor dialog box, find this subkey in the registry, and then click it:

    • HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Search

  3. Click Edit > New > DWORD Value.

  4. Type DisableServerAssistedSearch for the name of the DWORD, and then press Enter.

  5. Right-click DisableServerAssistedSearch, and then click Modify.

To search a Shared Mailbox, click the mailbox and use the Current Folder scope. This is a design limit that's currently being worked on for future updates. Go to this Understanding Search Scopes blog for more details about what scopes are supported when.

To work around this issue, you can add the Shared Mailbox as a secondary Exchange account to the profile. First you will need to check if the shared mailbox is already listed as an account in the profile. If so, you will have to remove it. To do this, follow these steps:

  • From the File menu, select Account Settings, then choose Account Settings again.

  • Double click the Exchange account.

  • Choose More Settings, and then select the Advanced tab.

  • In the Open these additional mailboxes section, choose the shared mailbox and then select Remove.

Add Shared Mailbox as a secondary account to the profile by following these steps:

  • From the File menu, select Add Account.

  • In this dialog put the full name of the mailbox, e.g. support@company.com.

  • When prompted for a password, choose the option Sign in with another account and use the Exchange account credentials that has permissions to the shared mailbox.

When you search a shared mailbox added as an additional mailbox you may see this error:

  • "We're having trouble fetching results from the server. Some items may not be included in your search results."

This will occur if you're using a perpetual volume license (MSI) version of Outlook. This is currently a limitation with perpetual versions of Office.

To work around this, you can disable server search as a short-term solution. To do this, follow these steps:

In Microsoft Outlook 2016 for Mac, you may receive a "No Results" message when you try to search for an email message or apply a filter to a folder, and task items are not displayed in the Tasks folder. Additionally, when you search for mail items by using the Mac OS native Spotlight Search, your search may be unsuccessful.

This could happen for the following reasons:

  • Spotlight Search indexing is incomplete.

  • The Profile name contains special characters such as the slash mark (/).

  • The Profile or one of its parent folders are added to the Privacy tab in Spotlight.

  • The Outlook 15 Profiles folder is not located under ~/Library/Group Containers/UBF8T346G9.Office/Outlook.

  • The Spotlight Search index is corrupted.

To resolve this issue, follow these steps:

  1. Run the OutlookSearchRepair utility.

  2. If you recently created a new Outlook Profile in Outlook 2016 for Mac, added a new account, or if you recently imported new data from a source such as a PST or OLM file, Spotlight indexing may not be complete. In this case, Outlook for Mac displays a "No Results" message. To resolve this issue, wait for indexing to finish, and then search again.

  3. Make sure that your Profile name in Outlook 2016 for Mac has no special characters, such as the slash mark (/).

To view your Profile or Identity name in Outlook 2016 for Mac:

  1. Click Go, Applications.

  2. Right-Click Microsoft Outlook, and select Show Package Contents.

  3. Expand Contents, SharedSupport, and open Outlook Profile Manager.


If the Profile or Identity name contains a special character, follow these steps to change the name:

  1. Open the Outlook 2016 for Mac Profile folder located at:  /Users/<Username>/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/

  2. Rename the Outlook 2016 for Mac Profile folder name and remove the special characters.

If the issue is still unresolved, the Spotlight index may be corrupted. To reindex the Spotlight index, follow these steps:

  1. Restart the Mac, so that it restarts the Spotlight services.

  2. Navigate to Finder > Applications > Utilities > Terminal.

  3. Type mdimport -L.

    Important: If you see more than one instance of "Microsoft Outlook Spotlight Importer.mdimporter," delete the Outlook application that you are not using, empty it from the Trash, restart your Mac, and go back to step 1..

  4. In the Terminal, reindex your Outlook database by using the following command and substituting your own user name for the <user_name> placeholder: mdimport -g "/Applications/Microsoft Outlook.app/Contents/Library/Spotlight/Microsoft Outlook Spotlight Importer.mdimporter" -d1 "/Users/<user_name>/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/<my_profile_name>"

    Note: In this command, the path after "-g" is the default path of the Outlook installation. The path after "-d1" is the default path of your profile, where <my_profile_name> is, by default “Main Profile." You'll have to substitute your actual paths if you have renamed your profile or installed Outlook in a different location.

Reindexing will take some time to complete. After the process is complete, exit and then restart Outlook. 

If you still cannot search in Spotlight after you follow these steps, and if you have allowed for enough time for Spotlight Indexing to be completed, you may have to uninstall Office for Mac and reinstall it.
