    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).

    Because the account works elsewhere, open Outlook.com in a Safari Private Window first, then reset Safari’s Outlook/Microsoft website data if the page still spins.

    Fix the Safari sign-in loop

    1. In Safari, select File → New Private Window.
    2. Open https://outlook.live.com/mail/ and sign in.
    3. If it works, the problem is isolated to Safari’s stored site data or an extension. Continue with these steps so Outlook also works in a normal window:
      • Select Safari → Settings → Extensions.
      • Temporarily turn off ad blockers, pop-up blockers, and privacy/content-blocking extensions.
      • Close and reopen Safari, then test Outlook again.

    Microsoft notes that ad blockers such as AdBlock and uBlock can prevent Outlook.com from loading correctly. On macOS, Outlook.com supports Safari 16 or later; updating macOS normally updates Safari as well.^1^

    Clear only the affected website data

    If it continues spinning:

    1. Select Safari → Settings → Privacy.
    2. Select Manage Website Data.
    3. Search for and remove entries associated with:
      • outlook
      • live
      • microsoft
    4. Close all Safari windows.
    5. Reopen Safari and sign in again.

    Removing website data signs you out of those Microsoft sites but does not delete email. Microsoft’s Outlook.com troubleshooting guidance recommends clearing Safari’s browser data, closing all browser windows, and signing in again.^2^

    If Safari blocks the authentication handoff, also check Safari → Settings → Privacy:

    • Temporarily turn off Prevent cross-site tracking.
    • Ensure Block all cookies is off.
    • Retry the sign-in.

    After Outlook loads, turn Prevent cross-site tracking back on and test again. If enabling it immediately brings the spinning page back, continue using another supported browser while Safari or Outlook is updated.

    If Safari still cannot open Outlook

    • Continue using the other browser that already works; this avoids unnecessary password resets or account recovery.
    • Check Microsoft’s Outlook.com known-issues page for a current service problem.^2^
    • If Safari fails even after its Microsoft website data and extensions are cleared, use the Outlook.com support link under Still need help? Microsoft provides a separate support route for users who cannot sign in.^3^
