No Incoming email settings on my Calendar List?

I actually have a similar question. I'm looking forward to creating a public calendar for my company out of a list result. Unfortunately, I couldn't find some good options since we have group permissions on the list. 

The only thing I found was to create a workflow that would add calendar events according to the list results but everyone part of the organization would receive calendar invites in their outlook inbox. Does anyone know a better way of doing this? Thank you!
