Please ensure you've read the introduction to importing calendars.
Who can see the events I import into Slack using Eventbot?
When you import an external calendar into a Slack channel, only the members of that channel will see the events. You can import calendars into public and private channels. You can share any individual event by clicking "Invite" and choosing the person or channel to share the event to.
Can I see all the external calendars imported into my workspace?
Not yet. To see which external calendars are being imported, you'd need to go into a channel and type "/events import". We'll update this as this feature evolves.
Can anyone see the URL of my imported calendar?
No Slack users can see the full URL that you used to import an external calendar. We hide this for security reasons, since calendars can come from personal sources. All Slack users will be able to see the domain of that external calendar (for example, google.com), but your URL will be hidden once imported.
