I use Outlook 2007 to manage my schedule and ncsy it with the iPhone via iCloud. To this I have two calendars in outlook: a standard name "Calendar" and other "calendar in icloud". only the "calendar on icloud" is successfully synced. When I receive an invitation via email from third parties, to accept it, the appointment appears only in the "calendar". How do I make the commitment to be marked in "calendar on icloud"? Thank you!
