Description
When users publish their calendar to Microsoft Office Online using the Microsoft Office Outlook Calendar Sharing Service, Outlook updates the calendars online at regular intervals unless they click Advanced and select Single Upload: Updates will not be uploaded from the Published Calendar Settings dialog box. If your organization has policies that govern the use of external resources such as Microsoft Office Online, allowing Outlook to publish calendar updates automatically might violate those policies.
