I have purchased the new Microsoft Office 365 Home premium. But I am unable to launch the Outlook from my Desktop. There is an error which is regularly coming. "Cannot start Microsoft outlook. Cannot open the outlook window. The set of folders cannot be open. The file C:\users\Indrajit\AppData\Local\Microsoft\Outlook\IndrajitMahurkar.ost is not outlook datafile(.ost)
How can I correct this and launch the outlook from my desktop.
