How to Share a Contact Group in Microsoft Outlook with Other Users

Contact groups (previously known as distribution lists) in Microsoft Outlook save tremendous amounts of time when you regularly email the same project team, department, or client circle. Rather than manually typing dozens of individual recipient addresses into the “To” line for every message, addressing an email to a single contact group automatically broadcasts it to everyone on the roster.

When onboarding a new colleague, transitioning project duties, or collaborating with another team lead, recreating an extensive contact group manually is tedious and prone to typos. Outlook provides a native forwarding mechanism that allows you to package and send an entire contact group directly to another user so they can import it into their own contacts in seconds.

Sharing a Contact Group via Outlook Desktop on Windows

If you use the classic Outlook desktop client, you can attach and forward a contact group as an Outlook item:

1. Open Microsoft Outlook and switch to the People (Contacts) view using the icon in the left-hand navigation bar.
2. Locate the contact group you wish to send. Contact groups are distinguished by an icon featuring two people standing side by side.
3. Double-click the contact group to open its properties window, or simply click to highlight it.
4. On the top ribbon, look for the Communicate or Share section and click Forward Group (or Forward Contact).
5. From the drop-down menu, choose As an Outlook Contact.
6. Outlook will automatically open a new compose window with your contact group attached as an .msg attachment.
7. Enter your colleague’s email address in the To field, add a subject line and brief note, and click Send.

How the Recipient Saves the Shared Contact Group

When your colleague receives the email containing the contact group, importing it into their personal Outlook directory requires just a drag-and-drop gesture:

1. Open the received email message containing the contact group attachment.
2. Click and hold the attached contact group icon.
3. Drag the attachment directly over to the People icon on Outlook’s left navigation rail, then release the mouse button.
4. Alternatively, double-click the attachment to open the contact group preview, click File > Save & Close, and Outlook will permanently store the group in their local address book.

Once saved, the recipient can type the group name into any new email draft to message the entire roster immediately.

Forwarding Contact Groups as an Internet Format (vCard)

If your recipient uses Outlook on macOS, a web browser, or third-party email software, forwarding as an Outlook proprietary item might occasionally display as an unrecognised attachment. In those circumstances, forward it as a standard contact file:

1. In Outlook’s People module, highlight the contact group.
2. Click Forward Group and choose As an Internet Format (vCard).
3. Outlook creates a standardised .vcf file containing the contact metadata that almost any modern email client or mobile device can open and import natively.

Important Note on Shared vs Local Group Updates

Forwarding a contact group sends a standalone snapshot of the group as it exists at that specific moment. If you subsequently add or remove members from your local group, those adjustments will not automatically synchronise to the recipient’s saved copy.

If your team requires a dynamic, centralised distribution list where membership synchronises automatically across everyone in the organisation, consider asking your Microsoft 365 administrator to create a shared Distribution List or Microsoft 365 Group via the Exchange admin centre instead.

For ad-hoc project teams and daily workflow handoffs, sharing your contact groups directly via email provides the fastest and most convenient shortcut available.
