Events that have a recurrence pattern work like recurring events in a calendar: when you turn on recurrence, a series of events is scheduled into the future, repeating on a daily, weekly, monthly, or yearly basis.
Recurring events in a series will share the same basic properties, attendee list, publishing points, and permissions. However, it's possible to modify the basic properties or the attendee list of one occurrence (event) within the series without affecting the rest of the series.
On the Basic tab, you can save changes to only one occurrence—or date—in the series. This is useful if you need to cancel or reschedule (or if you need to change the location or encoder for) just one event in the series. When you save changes for one occurrence only, the event becomes "detached" from the series of events. Additionally, if you publish an agenda for an event that's part of a series, the event becomes detached from the series as well, in order to protect the historical data. Changes to the basic properties or attendee list of a detached event do not affect the series; conversely, changes to a series basic properties or attendee list do not affect detached events.
Note: Changing the data on the Agenda tab does not detach the event, instead, the event becomes "protected." It is only when you publish the agenda for the event that it becomes detached. See below for more details about protected events.
Detached Events
The system behaves as follows once an event is detached from a recurring series:
What Happens if I...?
Answer
Edit another occurrence in the series and save changes to the series
The basic properties of the detached event will not be updated with the series. This includes changes to the recurrence pattern; if you change the schedule, detached events will not be updated.
Edit a detached event and save changes to the whole series
The series will be updated to reflect the detached event’s basic properties.
The changes to the attendee list apply to the series but not to any events that are detached from that series. See Adding Attendees to an Event.
Note: The Publishing and Permissions tabs do not change across a series; they function the same regardless of whether or not an occurrence is detached from the series.
Example
A recurring event for the City Council Regular Meeting is scheduled for the 2nd and 4th Tuesday of every month. You are notified that the meeting on July 9 is canceled, so you select the name of that event to edit it. On the event's Basic tab, turn off video recording for that date, and then add the word “Canceled” (or your preferred language) to the title in order to notify the public of the cancelation. When you click Save Changes, you will see this message:
Update event confirmation modal
Select Update only this occurrence to save changes to just this one date in the series. The July 9 meeting is now “detached” from the series.
This message appears on the July 9 event’s Basic properties tab:
Detached event message
The icon shown below appears next to the July 9 event in the Events list:
After this meeting has become detached, you need to update a few settings for the series. If you click the July 9 meeting and update the series, all events in the series would read “Canceled” and have video recording turned off. Instead, you should find the next event in the series, make the necessary changes, and select Update the series when prompted. This ensures that the series maintains the correct title and video recording options.
Protected Events
An event becomes protected when you load agenda data for that event. "Protected" in this context means that the event date will not change if you update the recurrence pattern for this series of events. Protected events are different from detached events in that if you update the basic properties or the attendee list for the series, the basic properties and the attendee list of protected events will also be updated (aside from the date of the event). For example, an encoder change will be updated, but a date change won't.
Example
If you have a series on the 2nd and 4th Wednesday of the month and change it to the 2nd and 4th Tuesday, the system deletes all events that don't have agenda data and creates new events for the new days. However, any events that include agenda data are left on their original Wednesday date.
