Outlook 2016 public calendar not updating
First, check the online calendars for appointments: If you see appointments online but not in your Outlook app, you'll need to add the or Office 365 account in Outlook.
The only options for syncing with Outlook for Mac right now are our Office 365 and Exchange integrations.
Unfortunately Outlook for Mac does not support internet calendar subscriptions, and our 1-way subscription will not work.
If you were using our 1-way Subscription before connecting the 2-way sync, you will continue to see appointments from the 1-way Subscription until you remove it.
If you're still having trouble, please contact us and let us know a specific event name, date and time that isn't syncing into Acuity Scheduling or your Outlook calendar.
This guide will show you how to create a new shared calendar in Office 365, and then share it with someone outside your organization.
