I'm not able to send bulk email on outlook. I can send and receive single emails on outlook. Tried to split bulk email into small chunks 80 at a time and still doesn't work

    Are you using the "New Outlook"

    It is just a re-badged version of Windows Mail and, like its predecessor, it cannot be used to send messages created by using the mail merge facility in Word,

    If that is what you are using, you will need to switch to the original Outlook by using the toggle switch at the top right of the Outlook Window

    If you do not see the above toggle, the toggle for Outlook Classic may be under Help:

    Hi, Ramon. Microsoft 365 Personal limits bulk sending to 300 recipients per day and 500 per message. Sending more will fail. Just keep within these limits or using distribution lists. Outlook may block repeated identical messages.

    It appears that you are experiencing issues with sending bulk emails in Outlook, even after attempting to split them into smaller groups. While the context provided does not specifically address bulk email sending issues, here are some general troubleshooting steps you can consider:

    1. Check Email Limits: Ensure that you are not exceeding the sending limits set by your email provider. Many providers have restrictions on the number of recipients you can send to in a single email or within a certain time frame.
    2. Use Mail Merge: If you are trying to send personalized bulk emails, consider using the Mail Merge feature in Microsoft Word combined with Outlook. This allows you to send individual emails to multiple recipients while maintaining personalization.
    3. Check for Errors: Look for any error messages that may appear when you attempt to send the bulk email. These messages can provide clues about what might be going wrong.
    4. Update Outlook: Ensure that your Outlook application is up to date, as updates can fix bugs and improve functionality. You can check for updates under File > Office Account > Update Options.
    5. Repair Office: If the problem persists, you might want to repair your Office installation. This can resolve issues that may be affecting Outlook's performance.
    6. Contact Support: If none of the above solutions work, consider reaching out to Microsoft support for further assistance.

    These steps should help you troubleshoot the issue with sending bulk emails in Outlook.
