## Outlook outage nearly over
Microsoft Outlook and 365 are recovering after an almost two-day outage affecting millions worldwide. Some users reported email access restored on Friday morning, though mail flow may be delayed.
## Not a cyberattack, Microsoft says
Microsoft said the outage was a technical issue not related to cyber or AI agents. The company found no evidence of malicious activity and described it as unrelated to DDOS attacks.

> This was a technical issue not related to cyber or AI / agents.
## Network upgrade caused the problem
The incident was introduced by an issue during an earlier network capacity upgrade that surfaced following a recent network change. According to sources, the outage is linked to Azure VNet config changes.
## Other services also affected
The outage's scope extended beyond Outlook to SharePoint Online, Teams, Copilot AI, and 365 apps. Microsoft restored services gradually to validate stability at each stage before continuing.
## Full report coming later
Microsoft apologised for the disruption and said it will provide a full post-incident report once its review is complete. The company is continuing to restore service to remaining customers and regions.

> We are deeply sorry for the disruption this incident has caused our customers and partners.
## Key takeaway

Microsoft's global Outlook outage, which lasted nearly two days and affected millions of users, was caused by a technical issue during a network capacity upgrade and was not a cyberattack.
