Is Microsoft outage fixed today or is Outlook still down? What happened to Microsoft 365, Hotmail and Claude, when will email services be fully restored and what is the latest outage status?

Is Microsoft Outlook outage resolved today? Latest Microsoft 365 update, Claude status and full timeline: No, the Microsoft Outlook outage has not been fully resolved as of Friday, November 13, 2026. Microsoft has reported early signs of recovery after more than 12 hours of disruption, but Outlook, Exchange Online and other Microsoft 365 services are still facing intermittent problems. The company has applied a patch to part of its infrastructure and is gradually bringing affected servers back online. It has not announced a time for full restoration.

Businesses have struggled to receive customer messages, employees have lost access to workplace tools and some government departments have reported disruption. The outage has also reached AI services. Claude and ChatGPT users have faced problems with tools connected to Microsoft 365.

Is Microsoft Outlook back up? Latest outage update

Microsoft is making progress, but the recovery is not complete. Its latest update on Friday morning said affected infrastructure was showing early signs of stabilisation. Server capacity, however, had not returned to normal.


The company has applied a patch to an upstream authentication and routing component. The change is designed to improve how users connect to Microsoft servers. Microsoft is testing the patch and extending it to more infrastructure as servers become available.

The recovery has been uneven. Some users can access their Outlook accounts, while others continue to report connection errors, delayed messages and problems sending or receiving emails. Microsoft has also extended its email timeout window to 48 hours to protect delayed messages during the recovery.

There is still no confirmed time for full restoration.

Microsoft 365 outage timeline: What happened on November 12 and 13?

The disruption began on Thursday, November 12, and continued into Friday. Microsoft's Exchange Online infrastructure was at the centre of the problem.

On Thursday, November 12, at around 11:17 a.m. EST, Microsoft recorded an Exchange Online incident. Users began reporting trouble accessing their mailboxes.

By around 1:26 p.m. EST, the disruption had spread across more Microsoft 365 services. Downdetector recorded nearly 130,000 reports of Outlook problems. Complaints came from 74 countries.

Microsoft started redirecting traffic away from affected infrastructure. The first recovery attempts brought some servers back online. Some of them became unresponsive again when traffic returned.

The company then tried further configuration changes and server recovery measures. Early attempts did not deliver the expected results.

On Friday, November 13, Microsoft reported better results after applying a patch to an authentication and routing component. It began expanding the recovery work. The company later confirmed early signs of stabilisation, while warning that service capacity remained below normal.

The outage has now lasted more than 12 hours and affected users across several regions. The Associated Press reported that user complaints had declined, although many customers were still experiencing problems.

Why is Microsoft Outlook still down?

Microsoft has identified problems with servers that unexpectedly became unavailable during automated health checks. This reduced the number of servers available to handle customer requests.

The remaining infrastructure then faced higher traffic loads. Some servers that had restarted also became unresponsive after traffic returned.

Microsoft has not published its final root-cause report. It has said there is no indication that the outage was caused by a cyberattack. The company is investigating the infrastructure and configuration problems behind the disruption.

Is Microsoft Teams, Word, Excel and OneDrive working?

The outage has affected more than Outlook and Hotmail. Microsoft 365 services that depend on Exchange Online have also experienced problems.

Outlook users have reported trouble opening inboxes and sending emails. Teams users have faced issues with some features. Copilot, SharePoint and OneDrive have also appeared in outage reports.

Word, Excel and PowerPoint were among the applications named in user complaints. This does not mean every desktop application stopped working. The main disruption involves Microsoft's cloud infrastructure and connected services.

Some organisations have continued using parts of Microsoft 365 while other features remain unavailable. The impact depends on the service and the region.

Is Claude down today? Latest Anthropic outage update

Claude has faced a separate login problem as well as disruption to its Microsoft 365 connector.

Anthropic reported that its Microsoft 365 connector was affected by Microsoft's outage. Users experienced failures with mail, calendar, SharePoint and Teams search functions. Claude for Outlook was also affected. Some users could not open the add-in or complete email and calendar actions.

Anthropic also reported authentication problems affecting Claude.ai and Claude Code on Friday. It deployed a fix and began monitoring the recovery.

These are two different incidents. Claude's own login problems should not be confused with the Microsoft 365 connector failure. The latter depends on Microsoft's infrastructure and may continue even when Claude itself is accessible.

When will Microsoft Outlook be fully restored?

Microsoft has not given users a confirmed restoration deadline. Its current plan is to restore affected servers in stages, monitor their performance and gradually increase traffic.

Bringing servers online does not guarantee that they can handle normal demand. The company has already seen some servers become unresponsive after traffic returned.

For now, Outlook users should check Microsoft's official Microsoft 365 service health page. Claude users can follow updates through the Anthropic status page.
