Does an email sent to a distribution list count as one email toward the daily limit

Question

So, there is a sending limit in Outlook. If I send an email to a distribution list of 300 users (say, all-employee-user @mycompany.com), does that email count as one or as 300 emails toward my daily limit?

Hi @Vu Nguyen ,

When you send an email to a distribution list in Outlook, the way it counts towards your daily sending limit depends on how the distribution list is stored:

1. Distribution Groups in Organization's Address Book: If the distribution list is stored in your organization's address book, it counts as one recipient. This means sending an email to a distribution list of 300 users will count as one email towards your daily limit.
2. Distribution Groups in Contacts Folder: If the distribution list is stored in the Contacts folder of your mailbox, each member of the group is counted individually. In this case, sending an email to a distribution list of 300 users will count as 300 emails towards your daily limit.
