Solution! Outlook 2010 Search Not Working – Add-in mssphtb.dll Disabled
Outlook 2010 Search Problem
If you have upgraded from Office 2007 to Office 2010 with Windows 7 OS you may have noticed that your Outlook Email search isn’t working. You type in the name of an email sender you are looking for and ‘no results’. Well, after searching forums and blog posts around the Internet, I finally figured out the solution.
I am posting it here so that hopefully it will be come easy to find for people experiencing this problem.
Applies to: Windows 7 OS with upgrade of Office 2010 with Outlook from Office 2007 or 2003.
Outlook 2010 Search Problem Diagnosis: It appears that the dll file mssphtb.dll which was used for Windows Search Email Indexer in previous versions of Office, does not work.. or is simply unnecessary for Outlook 2010. I think the latter is the case. I honestly cannot find a straight answer to this, but I am guessing this is the case because the solution to make the email search work right leaves that dll add-in disabled. So I guess its not needed.
The main problem that seems to occur after upgrading from 2007 to outlook 2010 is that windows indexing service gets turned off. This probably occurs during the upgrade process for good reason, but the installation script does not turn it back on. Again, this is observational analysis only, I have no concrete testing results, so take it for what its worth.
