Hi Stephen,
Thanks for using our plugins and welcome to the forums! Excellent question there!
It should be possible, yes. This is approx. what you will need to do:
1. Get the link to your calendar. It should look something like this: http://www.domain.com/events/?ical=1
You can get it if you go to a list or month view and scroll to the bottom. There should be a button saying “Export listed / month’s events”. Right click on that and Copy link location.
2. Open your Outlook and go to the calendar
3. On the Home ribbon go to Open calendar > From Internet (https://cloudup.com/cqdiI12nphS)
4. In the popup dialog paste in the link of your calendar that you copied before. Click OK a couple of times and you are done.
In order to refresh the calendar you will need to do a Send / Receive all folders.
Does this help? Let me know.
Cheers,
Andras
