How do I synchronize my agenda?

You set this up for yourself as a staff member — not for a roster with several people at once; an administrator arranges that via the Roster.

From the Agenda you can link a person's schedule to an external calendar app, so that appointments are updated automatically.

Linking

1. Open Activity > Agenda and choose the desired person.
2. Click the kebab menu (⋮) and choose Personal agenda sync.
3. Check at the top that the correct person is selected — the link is saved per person.
4. Under Link new account, choose Google Calendar or Outlook Calendar and follow the sign-in steps.

Once linked, the account appears under Linked accounts. Unlink an account by removing it there.
