Do not just delete the user

Leavers need a controlled process. Mailbox access, file ownership, shared Teams, MFA, devices and licences all need a decision.

Use a repeatable checklist

A repeatable process reduces security risk and avoids lost access to important business information.

  • Block sign-in
  • Reset sessions
  • Preserve mailbox data
  • Transfer files
  • Remove unnecessary permissions
