When running Microsoft Windows 7 together with Microsoft Office 2010 I experienced the following problem: Whenever I was trying to open a PST-file the Outlook process got stuck. The only way to get the machine back to start was to kill the outlook process. Result from this: the PST-file was corrupt and I was unable to start Outlook correctly. Solution on this: Use the tool “scanpst” (installed along with Outlook) and repair your PST-file. In the meantime navigate to windows -> control -> mail and configure your datacontainersettings for outlook. Remove the link to the pathologic PST file.
Now how in the world do we avoid this hanging outlook process? It seems that the indexing mechanismn of Windows 7 does not work togeher with PST-files. So tune up your indexing settings by
1. Disable windows search service via commandline tool “sevices.msc” (sledgehammer method)
2. Change indexing settings by disabling indexing only for file extension “PST” (smart method)
Hope someone out there can use this information..
