Microsoft outage: delays delivering to Outlook, Hotmail and Office 365
Resolved - This incident is resolved, and delivery to Microsoft mailboxes is back to normal.

From about 17:30 UTC on 12 November, Microsoft's mail service returned temporary errors for most delivery attempts. The cause was an incident on Microsoft's side (Microsoft incident EX1550543), and delivery to other mailbox providers was not affected. Microsoft's errors dropped sharply from about 13:30 UTC on 13 November. Delivery was back to normal rates by 14:35 UTC, and Microsoft's error levels have been normal since about 15:10 UTC (09:10 CST).

We queued all affected mail and retried it automatically. Most of it has now been delivered, and the rest of the retry queue will finish over the next few hours. You don't need to do anything, and you don't need to resend.

If your messages use a short expiration (TTL) setting, some may have expired before Microsoft accepted them. Those messages were returned as bounces and appear in your bounce events. You may want to resend any time-sensitive messages that expired.

Thank you for your patience while Microsoft resolved this issue.

Update - Delivery to Microsoft (Outlook.com, Hotmail and Office 365) has recovered

Delivery to Microsoft mailboxes is back to normal. Starting around 17:30 UTC on 12 November, an incident on Microsoft's side (Microsoft incident EX1550543) caused delivery delays. The errors from that incident have now returned to normal levels, and new mail to Microsoft is being accepted at normal rates and speed.

We are finishing the automatic retry of mail that was delayed during the incident. Most of it has already been delivered, and the rest is draining steadily. Some older delayed messages may still arrive over the next while. You don't need to do anything, and you don't need to resend.

If your messages use a short expiration (TTL) setting, some may have expired before Microsoft accepted them. Those messages were returned as bounces and appear in your bounce events.

Monitoring - Delivery to Microsoft (Outlook.com, Hotmail, Microsoft 365) is recovering

Microsoft is still recovering from its service incident (Microsoft reference EX1550543). The problem was on Microsoft's side. Our platform has run normally throughout, and delivery to other mailbox providers was not affected.

Since about 11:30 UTC (5:30 AM US Central), delivery to Microsoft recipients has improved a lot. Delivery volume is back in its normal range. We're also working through the backlog of mail that was queued during the outage, and those retries make up a large share of what Microsoft is accepting right now. About 3 in 10 delivery attempts to Microsoft are still being deferred, compared with more than 9 in 10 at the worst point. That's still above normal, so some messages to Microsoft recipients may take longer than usual to arrive while Microsoft finishes recovering.

Microsoft reports that recovery is moving forward across Europe, Asia Pacific and North America, and that some users may still see intermittent issues.

What this means for you: You don't need to do anything. We'll keep retrying any deferred mail automatically. If you set short expiration windows on your messages, some messages to Microsoft recipients may have expired before Microsoft accepted them.

We'll keep watching delivery to Microsoft closely and will post again once it's fully back to normal.

Microsoft outage: delays delivering to Outlook, Hotmail and Office 365
Resolved - Microsoft has confirmed an incident affecting Exchange Online and Microsoft 365 connectivity in all regions. It’s tracked as EX1550543, and you can follow Microsoft’s updates at https://status.cloud.microsoft/m365/referrer=serviceStatusRedirect.

Since about 17:30 UTC on November 12, Microsoft’s mail servers have been answering a large share of delivery attempts with temporary errors. This affects Outlook.com, Hotmail, Live, MSN and Office 365 recipients. The errors include “451 4.7.0 Temporary server error”, “421 4.3.2 The maximum number of concurrent server connections has exceeded a limit” and “451 4.7.700 PFA agent busy”. The problem is on Microsoft’s side and affects senders across the industry. SparkPost’s own systems are working normally.

Affected messages are not lost. SparkPost queues them and keeps retrying automatically, and many are already going through on a retry. You’ll see these attempts as delay events in your event data. Recipients at Microsoft may get mail later than usual until Microsoft resolves EX1550543. Delivery to other mailbox providers is not affected.

You don’t need to do anything, and please don’t send these messages again. Resending creates duplicates once the queued mail goes through. If you’ve set a short message expiration (for example on one-time passcodes), those messages may expire before Microsoft recovers.

We’re watching this closely and will post an update as soon as things change.
