In NAV 2013 using Cronus demo database and Email as Attachment, the following error comes up:
Unable to cast COM object type 'Microsoft.Office.Interop.Outlook.ApplicationClass' to interface type 'Microsoft.Office.Interop.Outlook._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{00063001-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
What is needed in order to resolve this error? We've compared Outlook add-in with different computers (the ones that work), stylesheets but nothing obvious seem to popup. Are there any prerequisites when using this feature?
