Managing personal Outlook.com account settings, security, and privacy

One agent told me they will put in a follow up ticket request on my behalf ... confirmation was sent on Sept 26 with no update, and I asked for an update October 3 with still no update.
I will assume you got a SIR Escalation Case number. If not, please advise. If so:
There is not anything else you can do while the review is pending. There is no publicly documented alternative recovery process beyond Microsoft's account recovery and support channels.
The fact that a follow-up was promised within 48-72 hours and has not arrived does not necessarily mean the case was rejected. Consumer account escalations can sometimes take much longer than the original estimate.
And, I'm sorry, but no one here can help. We can't see the status of internal support cases.
