Overview
- Microsoft rolled back a recent configuration change on Monday after widespread Outlook.com sign‑in failures and said telemetry shows services recovering.
- Outage tracker Downdetector recorded hundreds to more than 1,500 reports in the US and UK, with most complaints pointing to login problems.
- Many users encountered “too many requests” messages and unexpected sign‑outs that blocked access to their mailboxes.
- iPhone owners using Apple’s Mail app were instructed to re‑enter their Outlook or Hotmail passwords to regain access.
- Microsoft labeled the incident a consumer service degradation, and some users still reported trouble on Tuesday even after the company said systems were healthy.
