One question I get asked often is how can I add one event from the SharePoint calendar to my Outlook Calendar.
We are looking into some other options as well, but here is one way: Connect the SharePoint Calendar to your Outlook. View this Sway tutorial for instructions on how to do this.
Once you have connected the Calendar, view the SharePoint Calendar besides your own within Outlook. Drag the event that you want to copy, from the SharePoint Calender over to your own. You don’t need to place it exactly, just drag it over, and it will automatically add itself to the same timeslot as listed on SharePoint.
You can then turn off the view of the SharePoint Calendar by clicking the little checkbox next to the name of the calendar.
