Resolution

Bowdoin offers two types of email groups through Microsoft 365. Both allow you to send one email to a single address and have it delivered to all members, but they differ in capabilities and management.

Microsoft 365 Group

A Microsoft 365 Group is a collaboration hub that combines a shared inbox, shared calendar, shared file storage (via SharePoint), and an optional Teams channel — all under one group identity. Groups are the recommended option for teams and departments that want more than just a shared email address.

  • Who can be a member: Anyone with any email address, including people outside Bowdoin (guests)
  • Self-service: Any Bowdoin user can create a Microsoft 365 Group without contacting IT — see Create a Microsoft 365 Group in Outlook for Windows in the Related Articles section
  • Privacy: Can be set as Public (anyone at Bowdoin can join and view content) or Private (membership is controlled by owners)

Microsoft 365 Distribution Group

A Distribution Group is a simpler, email-only list. Messages sent to the group address are forwarded to all members, but there is no shared calendar, file storage, or Teams integration.

  • Who can be a member: Bowdoin email addresses only — external addresses cannot be added
  • IT request required: Distribution groups must be requested through IT via the Service Catalog
  • Moderation: Can be configured to require a moderator to approve messages before delivery
  • Management: Owners manage members through Outlook Online — see Manage a Microsoft Distribution Group you own in the Related Articles section
Which should I use? If your group includes or might include people outside Bowdoin, or if you want shared files and a calendar alongside the email list, use a Microsoft 365 Group. If you need a simple moderated mailing list for Bowdoin accounts only, use a Distribution Group.
