outlook.com has blocked my message and I am unable to email a group

The message you received indicates that you have hit the daily message limit imposed by Outlook.com to prevent spam. This limit is designed to protect users from unsolicited emails and can restrict the number of emails you can send in a day, especially when sending to groups.

To resolve this issue, you can try the following steps:

1. Wait for 24 hours: The daily limit resets after 24 hours, so you may need to wait before sending more emails.
2. Reduce the number of recipients: If you are sending to a large group, consider breaking it down into smaller groups and sending emails separately.
3. Check your account: Ensure that your account is in good standing and not flagged for any suspicious activity, which could further limit your sending capabilities.
4. Contact support: If you believe this is an error, you can reach out to Outlook.com support for assistance.

Keep in mind that these limits are in place to ensure a safe emailing environment for all users.

Hi Parklake,

Thank you for reaching out to Microsoft Q&A Forum.

I understand how disruptive it is when Outlook.com blocks a group message like that. I can also see Q&A Assist has explained the daily limit and provided some steps above. Have you tried waiting 24 hours since you received that message? Let me know if you've tried any of those steps or if you're still having issues.

In addition to that guidance, here are a few checks that may help:

1. Check two things that also cause blocks

• Mailbox/storage: If your Outlook.com storage is over quota, sending can be blocked. You can see Storage limits in Outlook.com
• Suspicious content patterns: Very similar subjects/links sent rapidly can lower reputation and trigger throttling

2. Check your account status

While waiting, verify your account isn't flagged:

• Go to: https://account.microsoft.com/security
• Review Recent activity for any security warnings
• Make sure there are no blocks or restrictions listed

3. Create Distribution lists

To manage large groups easier:

• In Outlook, add your recipients to New Contact Group before sending large mailings
• Split your full group into smaller lists (Group A, Group B, etc.)
• Please see this official guide: Create, edit, or delete a contact list (or contact group) in Outlook - Microsoft Support

For more details, you can check Microsoft’s official article on sending limits: Sending limits in Outlook.com - Microsoft Support

Hi, I understand how inconvenient this can be when you’re trying to reach your group.

The message you received means Outlook.com has temporarily blocked sending because you’ve hit the daily limit designed to prevent spam.

This usually happens if you send too many emails in a short time or include a large number of recipients in one message.

The easiest fix is to wait about 24 hours for the limit to reset, then try sending smaller batches or use the BCC field for privacy.

If you often need to email large groups, you might want to set up a Microsoft 365 Group or a distribution list instead.

Can you tell me roughly how many recipients you were trying to include and whether you’ve sent multiple group emails today?

That will help me suggest the best approach for your situation.

Regards,
Aron
