We are seeing a significant recovery in delivered emails to Microsoft accounts. Deliveries to some domains continue to fail, however we will continue to retry these deliveries on our normal retry schedule. Microsoft has indicated they are slowly rebalancing traffic to mitigate the issue so we should continue to see increased delivery rates over the next hour. We will continue to monitor the situation.

Update
We are continuing to see high volumes of failed email deliveries to Microsoft hosted email accounts across the platform. Microsoft is still having a major outage as per their status page:
Trackops will continue to attempt to retry failed email deliveries as per our normal "temporary" temporary failed email schedule. At this time you do not need to attempt to resend emails that have not arrived to users with Microsoft hosted email accounts.

It currently appears as if multiple Microsoft hosted email systems (including Outlook 365) are currently down, as per a Microsoft post on their X account here: https://x.com/MSFT365Status
