Outlook limit on sending emails?

Question

Outlook limit on sending emails?

Joseph C Martin 30

I have purchased a new lap top with Windows 365. I successfully set up a new Outlook account and an outlook email address. I sent two emails yesterday and on the third I got a message that I had surpassed the limit of emails to send. Today when trying to send the saved draft, I got the same message and have not sent any mail today, never had this before from other providers for sure. How do I resolve this issue?

Hi! The limit is usually time-based, for example, it can reset after 24 hours, and can also be triggered by rapid sending, sending the same text to multiple recipients, adding many links/attachments, or if Microsoft detects unusual sign-in/location activity.

First, wait for the cooldown and then try again; in the meantime, make sure your account security is fully verified: sign in at account.microsoft.com > Security and confirm your phone number/recovery email, enable 2-step verification if available

i had copied email addresses from another version of Outlook message that had names of the addressee in brackets before the address, i deleted the names and had only the addresses and it went. the verify comment is right, the software flagged as possible spam message and locked the account waiting to verify

I am having this issue since yesterday, and the multi-factor authentication is all set up. This is so frustrating, I need to send an email. I have had this account for over 20 years, first time ever is doing this. Please help.

the steps i took for mine to start working, I restarted the computer, tried a test email to a single addressee and it worked, tried the email from draft that wouldn't go and got the same message of over the limit of sending emails, i did as mentioned taking out bracketed names on my send to section, i reduced the number of recipients to 19 from about 25, i hit send and got a message that i needed to verify identity. a text was sent to my phone and after keying that code in I was able to send. I am not sure what part of that did it but now its working as normal. i hope this helps you.

I have have been using my outlook account working on a charity event for two years. I reached out to the participants on my list and was blocked. I got this message.

"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"

What is the limit? My list is about 40. This just happened last week!
