When someone leaves, disable (don't delete immediately) their M365 or Google account, remove them from shared mailboxes and Teams or groups, revoke app passwords and MFA devices, and change any shared passwords they knew. Keep a simple checklist so it's the same steps every time, regardless of who's doing the offboarding.
Coach's tip: disable first, delete a few weeks later — that gives you time to redirect mail and recover files without rushing.
