Ical not updating
The end user can publish a calendar with a “public” URL that is searchable.
The other option is a “restricted” URL with an obfuscated URL.
Give the policy a name and add a new “domain” called “Anonymous” and select an appropriate maximum level of access: After you’ve added the “domain” anonymous to the policy, make sure it’s enabled, then press Next.
On the next page you’ll be presented with the opportunity to add mailboxes now.
Now you know a little more about the new feature, let’s take a look at how it comes together from a user perspective, and how it’s configured by the admin.
The recipient then can simply refer to the calendar via a web browser, or by using any i Calendar compliant software or web app they can subscribe to the shared Calendar.
