Under the 'Planning' tab of your solicitation, it is possible to export the planning as either a .pdf file or an .ics file.
Using the .ics files you can easily copy the schedule into your own calendar program such as Outlook.
Importing an ICS-file into your personal agenda, means importing a copy of your solicitation planning at that moment in time. There is no real-time connection between your personal agenda and the solicitation planning, meaning no automatic updates to your changes. Please be aware that whenever you (or your colleagues) update the planning you'd have import it again.
