Microsoft reported signs of progress on Friday after a major global outage left millions of users facing connectivity problems across multiple regions.
The company said it had observed marginal success after applying patches and rebooting infrastructure as part of its recovery efforts.
In an update published on its Service Health Status page early Friday, Microsoft stated it was continuing to monitor activity across regions. The firm added that it was assessing server performance and evaluating measures to improve system capacity.
The company later reported improvements. It said its latest traffic optimisation measures had delivered positive results for service stability and increased capacity.
“Recovery efforts are ongoing across impacted infrastructure. We are seeing early signs of stabilisation, but service capacity has not yet returned to normal levels and health remains variable as traffic is carefully reintroduced,” the company said.
The developments offered relief after earlier recovery attempts failed to produce the expected results. The disruption had placed pressure on remaining infrastructure after unexpected server unavailability was identified as the main factor.
The widespread technical failure affected Exchange Online mailboxes and disrupted access to Outlook, Microsoft 365 and Teams across multiple regions.
According to Downdetector, the number of outage reports in the United States exceeded 97,000 for Outlook. Reports reached 38,000 for Microsoft 365 and 4,500 for Teams.
Microsoft stated it was not aware of any malicious activity linked to the incident. The firm said it would treat the disruption as a priority until services were fully restored.
The company pledged to publish a detailed post-incident report once the situation is resolved. The report will outline the root cause and measures to strengthen infrastructure resilience.
