🧐 Removing a user does not delete their calendar data

Calendar data exists independently of calendar users. 

Sub-calendars and calendar users are two separate things. 

A sub-calendar for Bob

As a calendar admin, you can create a sub-calendar for someone. This creates a scheduling space for that individual. 

A user named Bob  

You also need to add that individual as a calendar user. This is how you grant access to the sub-calendar you’ve created as their scheduling space. 

So you might have a sub-calendar named Bob Smith, and a calendar user named Bob Smith. While they have the same name, they are two separate things: 

• The Bob Smith sub-calendar contains the events (the data) for or related to Bob Smith; these events might be created by the user Bob Smith, or added by someone else (e.g. a supervisor or colleague).
• The Bob Smith calendar user can view and work with the events on that sub-calendar; he might also be able to view events on other sub-calendars, depending on how his access has been customized.

Removing access without losing data

If Bob Smith leaves the organization, the calendar administrator can revoke his calendar access immediately. This will prevent Bob from accessing the calendar. 

The sub-calendar named Bob Smith and all the events it contains will still be on the calendar. Even if Bob Smith (the user) created events on the Bob Smith calendar, the events will not be lost.
