Microsoft Outlook outage status: Is email working again? What's down, what's working and when will services resume?

Microsoft Outlook users continued to face email access problems on Friday, November 13, as the company worked to restore services following a widespread Microsoft 365 outage. The disruption, which began on Thursday, November 12, affected users attempting to access their inboxes, send or receive emails and connect to Microsoft Exchange Online. The outage was not limited to Outlook. Several other Microsoft services, including Teams, Copilot, SharePoint, Microsoft 365 and Defender, also experienced disruptions. Thousands of users reported difficulties accessing their work accounts, raising concerns among businesses and organisations that depend on Microsoft's cloud-based services.

Microsoft has acknowledged the disruption and is working to restore the affected infrastructure. However, the company has not announced a confirmed timeline for the complete restoration of all services.

Microsoft Outlook outage latest update: Is Outlook working again?

As of Friday morning, Outlook and other Microsoft 365 services were still experiencing disruptions, according to Microsoft's service health updates. Microsoft identified the email-related incident under reference number EX1550543. The company said users might be unable to connect to their Exchange Online mailboxes through multiple connection methods.


These include Outlook on the web, Outlook desktop, Exchange ActiveSync and REST-based connections.

In its latest update, Microsoft said it had been monitoring changes made to improve service availability but found that they were "not taking as expected". The company is now exploring alternative ways to increase infrastructure capacity as it deals with persistent imbalances in traffic management.

What is working and what is not working during the Microsoft Outlook outage?

The disruption has affected several services that depend on Exchange Online. However, not every Microsoft application or feature has stopped working. Here is a breakdown based on Microsoft's service updates:

1. Outlook and Exchange Online: Users may still experience problems accessing their mailboxes through Outlook web and desktop applications. Sending and receiving emails may also be delayed.

2. Microsoft Teams: Core messaging and online meetings remain largely functional. However, calendar-related activities, meeting scheduling and certain chat creation features may fail.

3. Microsoft Copilot: Users may experience difficulties loading Copilot Chat or receiving responses. Copilot features that need access to work emails, calendars and files may also be affected.

4. SharePoint Online: Features that depend on Exchange Online may experience problems. However, accessing files stored directly in SharePoint Online remains functional.

5. Microsoft To Do: Users may find that the application does not load properly or that certain operations fail.

6. Microsoft Defender: Safe Links may experience verification problems. Users may also encounter difficulties accessing certain Microsoft Defender portal pages.

7. Microsoft 365 applications: Some users may be unable to view recently used files. Other features that depend on Exchange Online could also experience disruptions.

Microsoft has also identified potential problems involving Microsoft Planner, Purview, Fabric, Graph and other enterprise services. Importantly, these are potentially affected services. The actual impact may vary depending on the user's location, account and the particular application feature being accessed.

What is Microsoft saying about the Outlook outage?

Microsoft has acknowledged that its recovery measures have not delivered the expected results. In its latest communication, the company said it had been monitoring changes introduced to improve service availability. However, these changes were "not taking as expected". Microsoft is now examining alternative approaches to increase infrastructure capacity. The company is also dealing with persistent imbalances in traffic management, which continue to affect service availability. The latest update indicates that Microsoft is still working to stabilise its infrastructure rather than moving towards a confirmed full restoration.

When will Microsoft Outlook be fully restored?

Microsoft has not announced a confirmed timeline for the complete restoration of Outlook and other affected Microsoft 365 services. The company is exploring alternative ways to increase infrastructure capacity after its earlier recovery measures failed to deliver the expected results.

Until Microsoft resolves the traffic management issues and stabilises its infrastructure, users may continue to face intermittent or persistent disruptions. For now, users should monitor Microsoft's official service health updates for information about further recovery measures and restoration timelines.

How to check Microsoft Outlook outage status

Users can follow these steps to determine whether Outlook is experiencing a widespread outage:

1. Visit Microsoft's official service health page.
2. Check the latest updates under Microsoft 365 and Microsoft consumer products.
3. Microsoft 365 business and enterprise users can also check the Service Health section in the Microsoft 365 Admin Center.
4. Look for incident reference EX1550543 for Exchange Online mailbox connectivity problems.
5. Check incident MO1550821 for the wider Microsoft 365 disruption.

Users can also visit Downdetector to check whether others are reporting similar problems.

If Outlook is not working, users can check their internet connection and try accessing their account through another supported method. However, switching devices or browsers may not solve the problem if Microsoft's underlying infrastructure remains affected.

For important work-related communication, users should consider alternative communication channels until email services become stable.
