    If the messages are stuck in Outbox, use this path:

    1. Go to Send/Receive and select Work Offline.
    2. Open Outbox in the navigation pane.
    3. For each of the three messages, either:
      • Delete it, or
      • Drag it to Drafts, open it, and remove any large attachment.
    4. If Outlook says it is still trying to transmit the message, close Outlook, reopen it, and repeat the step above.
    5. Go back to Send/Receive and clear Work Offline to return online.
    6. If the messages should send automatically but do not, check whether Send immediately when connected is enabled.

    A common reason for messages staying in Outbox is a large attachment. If the account is Outlook.com, attachments larger than 25 MB must be reduced or replaced with a OneDrive link.

    If using Outlook on Mac, the Outbox only appears when messages are waiting to be sent. If mail continues to sit there, check Tools and switch to Online if that option is available. In New Outlook for Mac, that Online/Offline toggle is not available.

    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).
