    Set olApp = New Outlook.Application

End Sub

I have tried a lot of combination. this works in 2007 and below version.

Answer 1

The error is REGDB_E_IIDNOTREG.

Is this a click-to-run Outlook 2013 installation?

Answer 2

I had done a re install of the Outlook 2013 and the same is now working.
