Abnormal Security Status

Resolved: Abnormal services have fully recovered for hosted US and EU customers using Microsoft 365, with recovery completed at approximately 20:40 UTC in the EU and 21:15 UTC in the US. Live email processing remains stable, and traffic has returned to normal levels. Abnormal engineers will continue to reprocess emails affected by the Microsoft outage to ensure message security. If customers experience further issues, please contact Abnormal Support at [email protected].

Monitoring: Microsoft services continue to show signs of recovery. For hosted EU customers, processing of newly received emails and previously delayed emails is operating normally, and all configurations have returned to normal. For hosted US customers, newly received emails are processing normally, while Abnormal continues to process the remaining backlog of emails affected by the outage. Abnormal engineers have increased processing capacity to accelerate recovery of this backlog. Abnormal will provide further updates as recovery progresses.

Identified: Abnormal has resumed processing newly received Microsoft 365 emails for approximately two-thirds of mailboxes for hosted US customers and 80% of mailboxes for hosted EU customers. Recovery remains ongoing, and affected services have not been fully restored. Abnormal engineers are working to restore processing for the remaining mailboxes and process emails that could not be retrieved during the Microsoft outage, prioritizing newly received emails and retrying previously unsuccessful processing attempts. Customers may continue to experience delays in email processing and protection while recovery progresses. Customers using Google Workspace remain unaffected. Abnormal will provide further updates as more information becomes available.
