Outlook Command Line Switches

Outlook is one of those programs that generally always works; but occasionally we get a machine where outlook does not open and it has really un-useful error messages.

Once such problem occoured today after a Microsoft Update; where the user could not open their outlook data file. (File was fine; could be opened on other computers) But would just quit Outlook with the error "Cannot start Microsoft Office Outlook, Unable to open the Outlook window"

After a few tips and tricks from around the place many of the registry "fixes" etc did not work; however I stumbled across a Site that has the complete list of command line switches for Outlook.

The one that I needed to use was "outlook.exe /resetnavpane" which regenerated the layout of the 3 navigation panes and then allowed Outlook to open successfully.

But there is a complete list of every switch on this site so check it out here:
