There is currently no confirmed Microsoft restoration time to convert to ACST; Microsoft reports an ongoing Microsoft 365 service degradation on 12 November 2026, but has not published a firm resolution deadline.^1^
Where to check for the next estimate
- Public status: Monitor Microsoft’s Service Health Status page above.
- Microsoft 365 administrators: Open Microsoft 365 admin center → Health → Service health → Active issues Microsoft is working on. Tenant-specific incident details and updates appear there and can be more precise than the public page.^2^
- If the admin center is unavailable, use the public status page.
Australia time conversion
If Microsoft subsequently publishes a time in UTC:
- ACST: add 9 hours 30 minutes.
- South Australia on 12 November: daylight saving normally means ACDT, not ACST, so add 10 hours 30 minutes.
A “next update by” time is only the time Microsoft expects to provide another status report; it is not necessarily the estimated restoration time.
