Identify the actual mailbox behaviour
Record the rule or forwarding destination privately, its visible scope and the time it was noticed. Do not send a test containing passwords or reset links to discover who receives it. Keep the provider's exact labels rather than assuming every rule forwards all mail.
A legitimate household or work arrangement can also create forwarding. Verify with the authorized owner or administrator before deleting a necessary managed rule. An unfamiliar label is a reason to investigate, not proof of a specific attacker.
Use the provider's compromise guidance
Official account-provider guidance can include reviewing forwarding, inbox rules, recovery methods and connected access as relevant to its system. Follow the process for the actual provider. Do not apply an Outlook menu path blindly to another mailbox or claim the television service controls those settings.
If credentials may be exposed, secure the email account through its established route with a unique secret and supported additional authentication. Preserve a recovery method before removing old access.
Check dependent account messages
Email can receive player, app-store and service recovery links. Identify those dependencies without copying their secrets into the incident note. A television that still plays through an old session does not establish that future recovery messages are private.
An illustrative mailbox can stop forwarding after an authorized correction while a previously copied reset link remains a separate concern. Removing the rule does not retrieve information already sent. Ask the relevant account providers about any access that may need revocation.
Verify the corrected access state
Review the actual provider's session and connected-application controls where applicable, then test normal sign-in and recovery. Keep rule removal, password change and session revocation as distinct completed actions. Do not claim complete containment from one successful login.
If the mailbox is managed by an employer or another administrator, use that owner's incident process. Retain safe dates and findings privately. The useful result is an understood message-routing state and controlled recovery access, not a player reinstall that leaves the mailbox's separate configuration untouched.

Does changing an email password automatically delete every forwarding rule?
Do not assume that. Review the actual provider's account-compromise process and relevant settings.
