Daily Message Limit Falsely Stopping One Important Email from being Sent

Mike Celentano 0

I have a very important survey to send to my working group. Most of them are blind copied. There are about 55 recipients. This email was blocked last week and is still being blocked this week. I can send other emails with no problem in the same day. I followed all troubleshooting suggestions: made sure each recipient was in my outlook.com contacts, make sure my account infor was up to date, make sure to use MS authenticator. Still it is blocked. It is blocked when I use the App on my iPhone, the App on my MacBook, and the Browser Outlook.

I need to send this email, it's a week late and Microsoft is needlessly holding it up!!

Help, please help!!

Hi Mike Celentano

Please note that our forum is a public platform, and we will modify your question to hide your personal information in the description. Kindly ensure that you hide any personal or organizational information the next time you post an error or other details to protect personal data.

I understand how frustrating this is, especially when the message is time-sensitive and you've already waited a week while trying the recommended steps.

A few questions to narrow this down:

What exact error message do you receive when the send fails?
Is your email address ******@outlook.com,@hotmail.com,@live.com, ******@msn.com address?
Are all 55 recipients the same recipients that you have emailed successfully in the past, or are some of them new contacts?

In the meantime, please try the following:

1, Reduce the recipient count and test

Instead of sending to all ~55 recipients at once, create a test email and send it to 10-15 recipients first.

Outlook.com may temporarily restrict messages that resemble bulk mail even when you are well below the documented recipient limits.

2, Review recent account activity

Go to: Microsoft Account Activity
Check whether there are any security alerts or unusual sign-in events.

A temporary sending restriction can be triggered by automated security checks.

3, Try sending a simplified version of the message

Remove any attachments, hyperlinks, images, or complex formatting and send a plain-text version to a small test group.

Sometimes the content itself can trigger anti-spam protections even when the recipient count is relatively low.

Hi Winnie,

Thanks. I've been trying to fix this and I am very frustrated with MS for impeding my work.

I also chatted directely with the help desk and they basically told me to wait 24 hours even after I told them I've tried that several times.

Here is the email message I get after I try to Send my email when it gets automatically sent to my Delete folder:

"Hello [Moderator note: PII removed] ,

The daily message limit helps us free the world from spammers--we're sorry that it's getting in your way.

Thanks, The Outlook.com Team"

I do not regularly email these members of my volunteer working group. But a couple of weeks ago I did add them all to my Outlook Contacts. That did not help.

Attached is a screen shot of the email I am tryign to send.

I am having trouble comprehending why I have to change this email into many emails to experimentlly determine how to get this simple task to work. I would think that MS employees would have a way to resolve this for their customers like me.

I hope you can help me resolve this and also fix this systemic issue for all customers who remain under the limit and yet get flagged like myself.

Hi Mike Celentano

Thank you for providing the additional details and the screenshot.

This appears to be a limitation being applied to the Outlook.com account itself rather than a problem with any particular device or app. Unfortunately, the public Q&A forum does not have access to account-level tools that would allow us to review or remove that restriction.

At this point, I recommend contacting Outlook.com Support again through the Outlook.com support channel while signed in to the affected account and providing the screenshot showing the daily sending limit warning:

Go to Contact Us - Microsoft Support

Select the product or service you're having issue with.

Click Get Home Support

Type a brief description of your issue in the search box.

Click Get Help and select Contact Support below.

Go to the Products and services tab and choose the appropriate product.

On the Category tab, choose the appropriate category or an alternative option.

Go to Confirm.

Look for and select "Chat with a support agent in your web browser" (during business hours) if available. Explain your situation clearly.

I realize this is not the resolution you were hoping for, but from the information provided, the issue appears to require investigation by Outlook.com support because the restriction is being enforced at the service/account level rather than by the Outlook applications themselves.

Thank you for your patience, and I hope the support team can help review the restriction on your account.
