Despite deploying a fix that reached approximately 98% of affected environments by midday, Microsoft has not provided a specific timeline for full service restoration.

The company is still investigating the cause of the outage, and while many users regained access by the evening, residual issues persisted.

Most users were able to access services again by the evening of November 25, with expectations for complete restoration by November 26.

Microsoft is investigating a significant global outage that has affected its Exchange and Teams Calendar services, as well as Outlook.

Reactions from users have been mixed, with some appreciating the unexpected break before the Thanksgiving holiday weekend.

Frustrations were voiced on social media, particularly regarding the status page indicating normal operations despite the widespread issues.

Although Microsoft claimed that over 90% of impacted environments received a fix, many users continued to experience ongoing problems.

This outage underscores the critical reliance on cloud services for business operations and the need for organizations to bolster their infrastructure against such disruptions.

This incident follows a previous major outage in July 2024 caused by a corrupted update from CrowdStrike, which had significant repercussions across various sectors.
