How to Manage Members and Owners of a Distribution List

Managing a Cloud-Based Distribution List (DL)

Overview

Owners of cloud-based Distribution Lists (DLs) can manage members, owners, and sender permissions in the Exchange Admin Center (EAC).

It is recommended that each distribution list has at least two owners so someone can manage the list if one owner is unavailable.

Note: This applies only to cloud-based DLs. Microsoft 365 Groups or mail-enabled security groups are managed differently.

Tips & Important Notes

  • Some groups may be Microsoft 365 Groups or mail-enabled security groups; these are managed elsewhere

  • Changes may take a few minutes to apply across Microsoft 365

Troubleshooting

  • Cannot see or edit DL: Check Groups I own; contact IT if missing

  • Changes not applied: Ensure you clicked Save and wait a few minutes

When to Contact IT

Submit an IT ticket for:

  • Any changes to the general tab 
  • Being added as the owner of a distribution list, when you do not see it under 'Groups I Own'
  • Questions regarding distribution list settings

Include the DL name and the requested change/inquiry.
