Check Microsoft’s service-health page and wait for the current Outlook incident to clear before changing either computer; the available status information indicates a Microsoft-side disruption affecting Outlook web access today ^1^.

Mobile access can continue working during a web-service incident because an app may use an existing session or a different service path.

What to do now

Open the Microsoft service-health page.
If Outlook or Microsoft 365 shows an incident, continue using the mobile apps and retry the computers after Microsoft reports recovery.
Use the current Hotmail sign-in address: outlook.live.com. Hotmail is now Outlook.com ^2^.

If service health is green afterward

Because both computers are affected, test whether the shared Internet connection is the common factor:

Connect one computer to a phone hotspot or another Wi-Fi network.
Open an Edge InPrivate window with Ctrl+Shift+N, then try Outlook.com.
If it works on the alternate connection, restart the home router and check whether a VPN, proxy, DNS filter, or router security feature is blocking Outlook.
If it still fails, test with an up-to-date Firefox or Chrome. Windows 11 supports current versions of Edge, Firefox, and Chrome for Outlook.com ^3^.
Temporarily disable AdBlock, uBlock, or other content-blocking extensions for Outlook.com. Microsoft notes that these extensions can prevent Outlook.com from loading ^3^.

If InPrivate works but a normal Edge window does not, remove the Outlook site cookies:

Open Outlook.com in Edge.
Select the icon to the left of the address bar.
Open Cookies and site data, delete Outlook/Microsoft site data, and reload the page ^4^.

If an error page appears, preserve its exact error number, UTC date, client/session ID, and BootResult. A persistent Error 500, BootResult: fail, or StartupData ServerError after service recovery should be escalated to Microsoft Support rather than treated as an Edge problem ^5^.

Welcome to Microsoft Q&A!

Hello,

What you are experiencing is currently linked to an active Microsoft 365 service incident tracked under ID EX1550543.

Microsoft initially reported intermittent connectivity issues affecting Exchange Online mailboxes in the Americas, and has since updated the advisory to confirm that the issue may impact general Microsoft 365 service connectivity across any region.

What this means for your environment:

Affected Services: Primarily Exchange Online / Outlook (desktop client, Outlook on the web, and mobile apps), along with potential authentication or connection timeouts across broader Microsoft 365 services (such as Teams, SharePoint/OneDrive, or the Microsoft 365 Admin Center) that rely on shared front-end connectivity infrastructure.

Action Required: No configuration changes are needed on your tenant or client devices. Microsoft engineering teams are actively working on mitigation.

How to track live status:

Open the Microsoft 365 Admin Center using a Global Admin or Service Support Admin account.

Navigate to Health > Service health.

Search for incident ID EX1550543 for real-time mitigation progress and root cause updates.(You can also follow official updates via @MSFT365Status on X).
