Rotate team email delegation without losing track

Switch which team members have delegated access to a shared mailbox, using a service account to automate rotation and audit.

The problem

Shared mailboxes often require rotating access among team members for coverage, but manual updates are error-prone and leave audit gaps. Relying on calendar reminders or spreadsheets to manage delegation leads to missed handovers, lingering access, and untracked changes.

How it works

  1. Maintain a source of truth (e.g., a Google Sheet or directory group) listing current and next-up delegates.
  2. Have a scheduled automation read the list and compare it to current Gmail delegation settings via the Gmail API.
  3. Add new delegates and remove outgoing ones using the service account, logging every action.
  4. Notify affected users before and after changes to catch surprises early.

What changes

Delegated access matches the intended rotation, with a clear audit trail and no manual steps required at shift change.

The trap in this one. The Gmail API's delegation changes can take several minutes to propagate, but the API returns success immediately. If you rotate delegates in quick succession (e.g., for testing or during an incident), new delegates may not gain access in time, or removed users may retain it longer than intended. Always allow for propagation delays, and confirm delegation via the API—not just the UI.

Questions people ask

How quickly do delegation changes take effect?

Propagation usually takes 2–15 minutes. For critical operations, confirm access before expecting delegates to act.

Can this work with more than one shared mailbox?

Yes, but each mailbox's delegate list must be managed and audited separately. Automate the mapping and rotation for scale.

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
