Outlook window/app will not open

[NHgranite]

Cannot open the Outlook window. Set of folders cannot be opened. Errors have been detected in the file i.e..ost file. To avoid any confusion, the problem is not is display but failure of application to launch and open. Not useable.



Uninstalled MS Office and reinstalled it. Outlook would not launch and still displayed the same message as shown in the attached pdf. Used the Scanpst.exe app in the program files for MS Office and it said it did a successful repair of the file. But when I click on the Outlook application it still fails to launch and I get the same error alert. What can I do?????????
