Exchange - Distribution List Rejects Messages from External Senders

Issue/Question

  • My distribution list is unable to receive messaged from external senders.

Environment

  • Oregon State University
  • Exchange Online
  • Distribution List

Explanation

By default, new distribution lists are configured with a setting requiring all senders to authenticate. In practice, this means that an Exchange distribution list will reject messages from anyone outside of OSU's Exchange instance.

Resolution

Contact your IT team to remove the setting from your distribution list.
