    Hi,

    Due to a lot of spam abuse, Microsoft has certain limits on sending emails, especially with a new account.

    Sending limits in Outlook.com
    https://support.microsoft.com/en-us/outlook/sending-limits-in-outlook-com

    What are the Outlook.com email limits?

    The limits for Microsoft 365 subscribers are:

    • Daily recipients: 5,000
    • Maximum recipients per message: 500
    • Daily non-relationship recipients: 1,000

    How can I increase sending limits?

    As well as taking a Microsoft 365 subscription, try these tips:

    • Make sure that all your information (like phone number and alternate email address) is updated on your account.
    • Make sure that you have updated your account's profile information (like Profile Name, Photo, Date of Birth, Gender, etc).
    • Make sure the password which you have created is a combination of upper case/lower case letters, numbers and special characters.
    • Make sure that the people you send emails to are added to your Contacts on Outlook.com.
    • Communicate frequently with your Contacts.
    • Use the Microsoft Authenticator app. The Microsoft Authenticator lets you quickly and securely verify your identity online, for all of your accounts.

    I hope this information helps. If you have any more questions, don't hesitate to reach out. Wishing you good luck!

    Outlook.com enforces sending limits to help prevent spam. The number of recipients allowed can be temporarily lower for newer accounts or accounts that have not yet established credibility.

    Supported Outlook.com limits for Microsoft 365 subscribers are:

    • Daily recipients: 5,000
    • Maximum recipients per message: 500
    • Daily non-relationship recipients: 1,000

    A non-relationship recipient is someone who has never been emailed before. Limits can be lower for non-subscribers, and can vary based on usage history.

    To improve or restore the allowed sending volume:

    1. Add recipients to Contacts in Outlook.com.
    2. Send to smaller batches instead of large groups.
    3. Communicate frequently with Contacts to establish credibility.
    4. Make sure account information is fully updated, including phone number and alternate email address.
    5. Update profile information such as profile name, photo, date of birth, and gender.
    6. Use a strong password with upper/lowercase letters, numbers, and special characters.
    7. Use the Microsoft Authenticator app.

    If the account was recently created, the lower sending quota is temporary and is increased as credibility is established.

    Also check these common causes if sending fails:

    • Attachments larger than 25 MB cannot be sent through Outlook.com.
    • Email signatures can sometimes interfere with sending; remove the signature and try again.
    • If a recipient is not receiving messages, ask them to add the address to their Safe senders list.
