The problem

Manual creation of shared calendars leads to inconsistent naming, missed permissions, and drift between departments. Bulk operations are tedious and error-prone, especially as departments restructure or new groups spin up.

How it works

  1. Fetch the current list of departmental groups from the directory.
  2. For each group, check if a shared calendar exists; create one if missing.
  3. Assign the group appropriate access (e.g. 'writer' or 'reader') to the calendar.
  4. Apply naming conventions and settings (e.g. time zone, description) programmatically.
  5. Notify group owners of new or updated calendars.

What changes

Departments receive correctly named, consistently configured shared calendars with the right access, and new groups are onboarded automatically.

The trap in this one. Creating a calendar and immediately assigning group permissions can silently fail: the Calendar API may not recognise the newly created calendar's ACLs for up to several minutes. If you script creation and sharing in one run, the group access is sometimes not applied, with no error returned—users then report missing calendars. Always re-attempt ACL changes after a delay or poll for propagation before proceeding.

Questions people ask

Can I update existing calendars to match new conventions?

Yes, but be aware that renaming or changing settings does not retroactively update calendar invitations or links users may have saved.

What if a department changes its group email?

You must update calendar ACLs to reflect the new group; old access is not automatically removed.
