send and receiving new messages problem

Question

Outlook cannot receive or send new messages since 4:41 AM this morning

Answer 1

Hello @stephen bruce baylin,

Thank you for reaching out.

To help me better understand what’s happening and narrow down the cause, could you please help clarify a few details below?

1/ Could you please share the email address that is affected. As this is a public forum and the information involves personal data, please share the email address via Private Message instead. I’ve already opened a Private Message for you, so kindly click “View message” to check it and reply there. This will help protect your information and allow us to communicate more securely.

2/ Have you tried signing in to your mailbox using Outlook on the web (OWA) or Classic Outlook app. If so, please let me know whether you are able to send and receive emails normally there, or if the same issue occurs.

3/ When you try to send an email, do you receive any non‑delivery report (NDR) or bounce‑back message. If yes, please share the exact error message or screenshot of that response, as it can provide important clues about the root cause.

These details will help determine whether the issue is related to the mailbox itself, mail flow, or the client being used.

Thank you for your cooperation. I look forward to your update so we can continue assisting you.

Kind regards,

Try the following steps in order for new Outlook for Windows:

1. Confirm internet connectivity
   • Open a browser (Microsoft Edge or Google Chrome).
   • Browse to http://www.microsoft.com or http://www.bing.com.
   • If these sites do not load, resolve the network issue first (see Fix network connection issues in Windows in the linked article).
2. Check if Outlook is offline or having sync issues
   • In Outlook, look at the status bar at the bottom. If there is an indication of working offline or not connected, reconnect the account/network.
   • Use the Sync button on the View tab (if available) to force a manual sync and watch the status message at the bottom while Outlook is syncing.
3. Verify password or app password
   • If the account password was recently changed on the email provider’s website, update it in new Outlook:
     1. Select the icon next to the email account name.
     2. When the sign-in pop‑up appears, select Continue.
     3. Follow the prompts and enter the current password.
   • If Outlook shows a message such as Please create an app password for Outlook on your email provider's site, go to the email provider’s site, generate an app password, then paste that app password when Outlook prompts for the account password.
4. If still not working, re-check account configuration
   • Use the guidance in Add an email account to Outlook for Windows to confirm the account is added correctly and completes setup without errors.

If none of these steps restore sending and receiving, follow the broader guidance in Troubleshooting Outlook issues for more in‑depth checks (profile, add‑ins, etc.).
