Outlook 2010: “Cannot start Microsoft Outlook. Unable to open the Outlook window. The set folders could not be opened. The server is not available. Contact your administrator if this condition persists”

This wonderful heavenly Outlook message brings loads of joy to the user when he/she sees it. You could create a new Outlook profile, but there is a better way.

Click Windows Key+R to open Run dialog and type the following.

Outlook.exe /ResetNAVPane

It should resolve the issue by recreating the folders.  If Yes, so say YES!!!



  1. No. My error msg is slight different: “Cannot start Microsoft outlook. Cannot open the Outlook window. The set of folders cannot be opened. The information store could not be opened.” Any other suggestions?


  2. No joy, still error message (before you get any options to reset folders). On a terminal server it seems to affect all users of that server.
