    For a sudden stop in email after 2 days, start with the checks that most often block mail flow:

    1. Sign in to Outlook on the web and check whether new mail appears there.
      • If mail appears on the web but not in the Outlook app, the issue is with the app connection.
      • If mail does not appear on the web either, the issue is with the mailbox or mail delivery.
    2. Check mailbox storage.
      • In Outlook.com, open Settings > General > Storage and confirm the mailbox or Microsoft cloud storage is not full.
      • A full mailbox can stop new mail from being received.
    3. Check whether the account is blocked for verification or password issues.
      • Try signing in to the Microsoft account in a browser.
      • If prompted to verify identity or update the password, complete that step first.
    4. Check Outlook web settings that can redirect or hide mail.
      • Review Settings > Mail > Rules
      • Review Forwarding
      • Review Junk email and blocked senders
      • Also check Deleted Items, Archive, Other, and any custom folders.
    5. If sending is also failing in Outlook desktop, check the Outbox for a stuck message and make sure Work Offline is not enabled.
    6. Send a test message from another email account.
      • If it does not arrive anywhere, and storage is available, the mailbox likely needs support-side investigation.

    For speaking to a human support agent for Outlook.com mail delivery issues, use this path:

    • Sign in to Outlook.com
    • Select the Help icon in the upper-right corner
    • Search for cannot receive emails
    • Scroll to Still need help? and select Yes
    • Choose Chat with a support agent in your web browser
    • Confirm the request to create the service ticket

    If the problem affects a custom domain mailbox, a DNS issue can also stop delivery.
