On January 22, 2026, Microsoft experienced a widespread issue impacting several Microsoft 365 services, including email, Microsoft Defender, and Microsoft Purview. This disruption affected many organizations across North America, including some of our clients.
What Happened
Microsoft first acknowledged the issue via its official Microsoft 365 Status channel at 1:37 p.m. CST, noting problems impacting multiple 365 products.
By 2:17 p.m. CST, Microsoft reported that:
“We’ve identified a portion of service infrastructure in North America that is not processing traffic as expected. We’re working to restore the infrastructure to a healthy state to achieve recovery.”
At 2:53 p.m. CST, Microsoft advised that they were:
“…continuing to review what actions are required to restore the affected infrastructure to a healthy state and rebalance the service traffic to achieve recovery.”
Later in the afternoon (4:15 p.m. CST), Microsoft shared that they were:
“carefully rebalancing traffic across all affected infrastructure in the region, while monitoring the corresponding health telemetry, to ensure the environment enters into a balanced state as our remediation efforts continue. We’re proceeding as quickly as possible and this incremental approach will also help us identify whether any additional actions may be required to ensure longstanding recovery.”
Since then, Microsoft has announced that the email outage has been resolved and services have been restored.
Impact to Our Clients
During the outage window, some of our clients may have experienced:
- Difficulty sending or receiving email
- Delayed message delivery
- Occasional bounce-backs or connection errors
Now that Microsoft has completed its remediation and rebalanced service traffic, normal email operations have been restored. Some users may still see slight delays as lingering queues clear, but these should be temporary.
What We’re Doing
Our team has been:
- Monitoring Microsoft’s official 365 Status communications throughout the incident
- Verifying that our email and related services are stable and operating normally
- Reviewing logs to identify any messages that may have been delayed or queued during the disruption
We will continue to keep an eye on the environment to ensure there are no recurring issues or residual impact.
What You Should Do
At this time, no action is required from our clients. However, we recommend:
- Checking your Sent and Inbox folders for any important messages that may have been delayed
- Re-sending any critical emails that appear not to have reached their recipient
- Letting your internal teams know that the issue was external (Microsoft infrastructure) and has now been resolved
If you notice any ongoing problems—such as missing messages, unusual delays, or repeated bounce-backs—please contact our support team so we can investigate.
We’re Here to Help
We understand how critical email is to your daily operations, and we take any disruption very seriously—even when the root cause is outside our own systems.
