Creating, Renewing, and Deleting MCommunity Groups

Members of the U-M community can create MCommunity groups to use for sending email, sharing U-M Google resources, authorizing access to resources, and more.

Creating a Group

  1. Go to the MCommunity Directory and log in with your uniqname and UMICH (Level-1) password.
  2. On the directory's home page click My Groups.
  3. Near the top left area of the page, click Create a Group.
  4. Enter a name. Group names:
    • Must be between 9 and 60 characters long.
    • Can contain any letter or number.
    • Can contain spaces, single quote marks (') and dashes (-).
    • Should be descriptive and easy to read.
    • Cannot contain other special characters, such as dots.
    • Cannot end with a single quote mark, or the group creation will fail.
  5. We recommend that you separate words in your group name with spaces. Then, when you send email to the group, you can substitute dots (.) for the spaces in the email address. Once your group has been created, you cannot change the name, so choose it with care.
  6. Enter an email address for your group. The group email address:
    • Must be between 9 and 64 characters long (excluding the part).
    • Should be something that is quick and easy for people to type when sending mail.
    • Can contain letters, numbers, dashes (-), and dots (.), but no other characters.
  7. The will be added for you. The address you enter here will be reserved for your group; MCommunity makes sure the address is not already reserved for another group before saving it. Once your group has been created, you cannot change the email address, so choose it with care.
  8. Enter a description for your group.
    • You cannot change your group name once it has been created, so choose carefully. The name will be displayed in search results and on the group's profile page.
    • Enter the email address you'd like to use for sending mail to your group.
    • The description will appear on the group's profile page. You will be able to make changes to the description after you create the group.
  9. Select your group settings, then click Continue.
    Important! Your group members depend on you to protect their privacy regarding membership in your group. While it is appropriate and preferable for some groups used for university business to have public member lists, there are situations where it is more appropriate to make the member list viewable by members only. Please refer to our appropriate use guidelines and respect the privacy expectations and preferences of your group members when selecting how visible the member list should be.

    Warning! If the group is self-joinable, anyone will be able to circumvent the "only viewable by members" setting by joining the group.
  10. After creating your group, you will be directed to its MCommunity entry. As the owner, you will have the ability to edit the group from this page. Add members to your group using the Add Members button, and assign Member and Owner roles as appropriate. When you are done, click Save.
    • For individuals affiliated with U-M, enter uniqnames in U-M Member.
    • For directory groups, be sure to enter the group's name (not its email address) exactly as it appears in its group profile. If, for example, the group name is made up of more than word with spaces inbetween, enter the spaces; adding dots between words will not work.
    • You can add external members who do not have a U-M email address in External Member. Add them by typing in their full email address.
    • It is a good idea to have several owners for your group in case one of you is away when a change needs to be made. You can have another group be the owner of your group if you wish. This allows the members of the owning group to make changes and renew the group.
    • There are two ways to add members to your group. You can enter uniqnames, group names, or, for people outside U-M, full email addresses.
  11. You will see your new group profile.

You can make changes to your group at any time:

Renewing Groups

To Renew a Single Group

  1. Navigate to My Groups and click Renew to the right of your group. Alternatively, view the group’s profile and click Renew below Settings.
  2. You'll see confirmation that the group was renewed, along with the new expiry date one year from today.

To Renew Multiple Groups

You cannot renew multiple groups at once, but you can renew them fairly quickly by looking at the list of all your groups. Click the Renew icon to the right of a group name to renew a group.

Deleting Groups

Important! Only the owner of a group can delete it. If a group has multiple owners, please check with the other owners before deleting it. You must be logged in to the directory to delete groups.

To Delete a Single Group

  1. View the group's profile, under My Groups. Then click the Delete Group button below Settings on the left side of the page.
  2. In the confirmation dialog box asking if you are sure you want to delete the group, click Delete.

To Delete Multiple Groups

You cannot delete multiple groups at once, but as the owner you may be able to delete them fairly quickly using the My Groups page. A Delete Group button will appear to the right of any group you have the authority to delete.

Important! You must be an owner of a group to renew it. You must be logged in to the directory to renew groups. Groups must be renewed on an annual basis. For details, see MCommunity Directory Group Expiry Policy.

Disabled Groups

Directory groups expire after one year unless they are renewed. When a group expires, it becomes disabled. At that point, all group functions stop working except the ability to find the group when searching the directory. Mail sent to the group will be returned to the sender as undeliverable; the error message will say that the group does not exist. If the group is used for authorization (for example, to allow access to a restricted web page), the authorization will fail.

The group owner(s) and the ITS Service Center can renew expired groups that are disabled.

You renew a disabled group the same way you renew any group that you own—by clicking the Renew Group button.

Note: Directory groups are sometimes disabled in response to complaints from group members when use of the group violates university policy. Owners are not able to renew groups that are disabled for policy violation.
