JSM Change Calendar: Sharing options

Customer is requesting option to share the change calendar with customers:

Is there a way to share this change calender with everyone in the organization by sharing the url to it? or any other option?

I know one option would be to create an organization and add every employee to that organization. However I was looking for some better solution where people can directly look at the calender (like outlook calender or any other shared calender) and find out if there is any change happening in the network or not.

I'd like the change calender to be viewed within the organization to other stakeholders even if they are not part of the project/Team.

Does JIRA have any integration with outlook in this regard?

I'm aware there's already JSDCLOUD-10822 for export and subscription options, but it was assumed that would still have security/permission requirements that only those who were agents/internal could still view.
