One service has a problem right now.

From Microsoft: Users may be unable to connect to multiple Microsoft 365 services.

We've begun returning a portion of the affected servers to service, and they're remaining stable so far. We’ve also shifted traffic and connections to alternative pathways wherever possible and have observed limited recovery in some regions.

We've streamlined our recovery process to expedite returning the remaining affected servers to service. To further support recovery, we're implementing protective traffic management measures in a specific location to reduce load on the affected infrastructure, and we'll expand these measures to additional locations if we observe positive results. As capacity is restored, users may experience a gradual recovery as their clients reconnect to the service.

Microsoft's next update is due by 7:30 pm (Manitoba time).

From Microsoft: Users may be unable to connect to multiple Microsoft 365 services.

We’re continuing to pursue all available pathways to restore service, as our actions taken thus far have not provided the anticipated relief. Our investigation has found that a core process on the affected servers is becoming overwhelmed, which causes the servers to stop responding and contributes to the capacity loss.

To validate a potential recovery approach, we're fully isolating a portion of our service infrastructure, restarting the affected components, and gradually reintroducing traffic to confirm our services remain stable before applying this approach more broadly. We're also analyzing traffic patterns across our entire service infrastructure and evaluating whether isolating traffic within each region may allow affected regions to recover independently.

Microsoft is experiencing an Exchange Online outage. Email may be delayed or fail to send or receive in Outlook, on the web, and on mobile devices. This is a Microsoft-side issue and nothing is wrong on your end. There's no need to restart devices or resend emails yet. Prairie IT is monitoring it and will update this page as Microsoft makes progress.
