# set_mailboxes_login_access

Suspend or restore sign-in across many mailboxes; delivery is unaffected either way. Choose exactly ONE of: mailbox_ids, domain_id (every mailbox on that domain — the usual choice for one client), or all. Shared, paused and trashed mailboxes are skipped and counted. Mailboxes already in the requested state count as matched but not updated, so the call is safe to repeat.
