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).

Open Outlook.com in an InPrivate or Incognito window first; if the mailbox opens there, disable browser extensions and clear only the Microsoft/Outlook site data.

1. Test the browser session

Open a private window:
- Microsoft Edge: menu … → New InPrivate window
- Chrome: menu ⋮ → New Incognito window
- Firefox: menu ☰ → New private window
Go directly to https://outlook.live.com/mail/.
Sign in with the Hotmail address and Microsoft account password.

If it opens in the private window:

Disable ad blockers, pop-up blockers, and privacy extensions for Outlook.com.
Clear cookies and cached site data for Microsoft and Outlook sites.
Close all browser windows, reopen the browser, and try again.

AdBlock and UBlock can prevent Outlook.com or messages from loading.^1^

2. If it still does not open

Update or test another supported browser:

Windows 11: current Edge, Chrome, or Firefox
macOS: current Edge, Chrome, Firefox, or Safari 16+
Linux: current Chrome or Firefox

Older browser versions may show an error page instead of loading Outlook.com.^2^

Also try Outlook.com from another device or network. The result identifies the next path:

Works elsewhere: the original browser, extension, or network is the likely scope.
Fails everywhere after successful sign-in: check the Microsoft service status. If it is not green, wait for service restoration before retrying.^3^
Cannot complete sign-in: use the Microsoft account sign-in troubleshooter linked from Microsoft’s Hotmail sign-in page. The same page covers blocked accounts and identity verification when a new device or location triggers a security check.^3^

If none of these paths resolves it, record the exact screen text or error code and whether the page is blank, continually refreshing, or rejecting the password. Do not post request IDs, email addresses, or other account information publicly.
