Mail-enabling a CornellAD group allows the group to be used in two additional ways.

• The group can be used in setting calendar and folder sharing permissions for Exchange accounts, whether NetID accounts, Exchange Group Accounts (EGAs), or Resource accounts. Anyone in the Cornell Exchange environment can give sharing rights to any mail-enabled group.
• The group can be used as a recipient for email messages or calendar events (by putting the group name in the To, Cc, or Bcc field). Messages sent to the group are delivered to all members of the group.

The lowest-level CornellAD reference groups (Node 9) have been automatically mail-enabled and can by used to set Exchange permissions by anyone with an Exchange account. See our Mail-Enabled Reference Groups article for more information.

Only CornellAD OU administrators and group owners can mail-enable a group. (How do I know who my OU administrator is?)

If you have an existing group that meets your mail-enabling needs, there is no reason to create a new group. A single CornellAD group can be used for many purposes, so long as the membership of that group is appropriate for all the ways you use it. Follow the steps in our Create a Group article.

Configuring an Existing Group Using the ARS Console

6. Click Next on the Welcome screen.
7. On the Available Tasks screen, select Establish an e-mail address, then click Next. (If you don't see this choice, but do see Delete E-mail Addresses, this group has already been enabled, so just Cancel out of the wizard.)
8. On the Establish an E-mail Address screen click Next. Do not change the Alias field.
9. There may be a noticeable delay while the task is completed. Click Finish to close the Exchange Task Wizard.

The group can now be used to set permissions or as a recipient for messages.
