Email recipients limits

Question

What are the limits on number of recipients i can send an email to?

Answer 1

In Microsoft 365, the limits on the number of recipients you can send an email to are as follows:

• Recipient limit per message: You can send an email to a maximum of 1,000 recipients in total, which includes recipients in the To, Cc, and Bcc fields.
• Recipient rate limit: You can send emails to up to 10,000 recipients per day. Once this limit is reached, you won't be able to send more messages until the next day.
• Meeting invitations: When sending meeting invitations or updates, the maximum number of recipients is 5,000 for any outgoing meeting message.

These limits help manage email flow and prevent abuse of the email system.
