## What changed

**1. Added: Update** (monitoring) · 2026-11-13 00:49 UTC

```diff
+ Microsoft is still working to resolve the incident affecting email delivery to Microsoft 365. Emails to Microsoft-hosted addresses may continue to show a “Delivery Delayed” status. There’s no need to retry them: we’re retrying automatically, and they’ll be delivered once Microsoft is accepting mail again. We’ll post another update as Microsoft’s status changes.
```
