Sending limits in outlook com

To help protect against abuse by spammers, Outlook.com limits the number of email messages that you can send in a single day, as well as the number of recipients for a single message.

If you recently created a new Outlook.com account, a low sending quota is a temporary restriction which is upgraded to the maximum limit as soon as you establish credibility in the system. 

What are the Outlook.com email limits?

Limits for non-subscribers vary on usage history. The limits for Microsoft 365 subscribers are:

• Daily recipients: 5,000

• Maximum recipients per message: 500

• Daily non-relationship recipients: 1,000

  Notes: 

  • A "non-relationship recipient" is someone you've never sent email to before.

  • The sending limits of any third party connected accounts depend upon the service provider.

What's the file attachment size limit in Outlook.com?

How can I increase sending and storage 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.
