Check eligibility
Open the organisation’s Mail settings using the required management permissions. The selected package must provide a shared-mailbox allowance and suitable storage.
Shared mailboxes do not consume human subscription seats, but the people assigned to them need the licences required by the application. A shared mailbox is different from an alias.
Create and assign
Use the mailbox-creation form, select Shared mailbox and complete the name and address fields offered for your verified, prepared domain.
Review Shared mailbox members and choose eligible licensed members, then Save assigned members. Wait for confirmation before testing access.
Assigned people open the business mailbox through their own identity. Do not create a shared password or distribute someone else’s recovery codes.
Changes and offboarding
Review mailbox state, domain readiness and device setup if a member cannot open it. Remove unneeded assignments through the available controls.
Suspending a mailbox retains stored mail and key/address reservations as described by the interface. It is not the same as deleting a business or permanently erasing all data.
