I recently received an error message that I had never seen before. After clicking the Microsoft Outlook icon on my Windows PC to open it, I wanted to search for a specific email. I clicked in the search bar – and as soon as I did, I received the following error message:

Instant search is not available when Outlook is running with administrator privileges. To use instant search, exit and start Outlook without administrator rights

Restarting Outlook did not help. I had run Outlook without administrator rights – although I may have been logged in as an administrator.

In any case, here are some steps you can try to solve the problem:

1] Exit perspectives. Ensure that the process has been stopped using the Task Manager. Restart Microsoft Outlook.

2] Restart your Windows computer and verify that the problem is solved.

3] Check whether Run as administrator was accidentally enabled in the compatibility options. Open the following location:

For Windows 32 bits, the path is C:Program FilesMicrosoft OfficeOffice14. For 64 bits Windows, the path is C:Program Files (x86)Microsoft OfficeOffice14. Right-click OUTLOOK.EXE and click Properties. Under Compatibility, deselect Run as administrator and click OK.

Start Outlook and check if it is resolved.

4] Change your user account and check if the problem persists. Try a standard account.


6] Check your Outlook add-ins. Try to selectively disable and see some of them. To do this, proceed as follows: File > Options > Add-Ins. If you have the SharePoint and TeamViewer add-ins, turn them off and check the box.

7] Make sure Outlook is configured as the default email client. Did it help you? You can do it here: File > Options > General > Make Outlook the default program for email, contacts and calendar.

8] Rebuild the index cover.

9] Save the file mssphtb.dll again. this is the Outlook MS Search Connector file. Please note that the Windows Search Email Indexer is not required for searching in Outlook 2010. If you are using Outlook 2007, you may need to do so.

If this has helped you, please let us know which proposal is available.
