Recruiters often need to send emails to many people when sharing job opportunities, collecting updated candidate information, or reaching out to potential clients. However, using Microsoft Exchange or Microsoft 365 to send a large volume of emails can present real challenges. Let’s talk about the limitations and best practices for safely and effectively sending recruiting mail with a Microsoft account.
Understanding Microsoft’s Limits
The most important restriction to understand are Microsoft’s limits on the quantity of emails that you can send with Exchange and Microsoft 365. Here are the key limits recruiters should know about:
As of January 2025, only 2000 external recipients per 24-hour period can be emailed from an Exchange Online account.

The maximum number of individual email recipients you can send to in a 24-hour period. This limit is currently 10,000 recipients total, but only 2,000 of those recipients can be outside of your own domain. This is a new change taking effect as of in January 2025.
The maximum number of recipients allowed allowed in the To:, Cc:, and Bcc: fields for a single email message. This is customizable up to 1,000 recipients.
