E-mail Messages in Outlook 2007 Cannot Be Indexed or Searched When Elevated User Rights Are Used
Updated: November 16, 2009
Applies To: Windows Server 2008 R2
When User Account Control is enabled on a computer running Windows Vista or Windows 7 and you run Microsoft Office Outlook 2007 by using elevated user rights, you cannot index or search e-mail messages.
This problem occurs because the SearchProtocolHost.exe process cannot open the same handle to the personal folders (.pst) file that Outlook 2007 uses. Outlook 2007 uses this handle when you run Outlook 2007 by using elevated user rights.
There is no resolution for this problem. This problem occurs in Outlook 2007 when used with the following operating systems:
Windows 7 Professional
Windows 7 Enterprise
Windows 7 Ultimate
Windows Vista Business
Windows Vista Enterprise
Windows Vista Ultimate
