    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).

    If this is classic Outlook, make it online again with these steps:

    1. Open Outlook.
    2. Go to the Send/Receive tab.
    3. Select Work Offline.
      • If Work Offline is highlighted or shaded, Outlook is offline.
      • Select it once to reconnect.
    4. Check the status bar at the bottom of Outlook.
      • If Working Offline disappears, Outlook is back online.
      • If it still shows Working Offline, select Work Offline again.

    If Outlook shows Disconnected instead of Working Offline:

    1. Confirm the internet connection by opening a browser and checking whether a site such as Microsoft or Bing loads.
    2. If webmail works but Outlook does not, Outlook may need updates or the account settings may need attention.
    3. Install Outlook updates.
    4. If needed, create a new Outlook profile. If the new profile is still disconnected, remove the account and add it again.

    If the Send/Receive tab or Work Offline button is missing, that can happen with some Microsoft 365 or Exchange setups when Cached Exchange Mode is turned off.

    Also note: Office Home 2024 does not include classic Outlook. If classic Outlook opens with a product notice or update loop, the issue is the license, not the offline setting. In that case, the supported option is to use new Outlook as the default mail app, or use a license that includes classic Outlook.
