    General

    Use this section to view or change basic information about the group.

    • Name: This name appears in the address book, on the To line when email is sent to this group, and in the Groups list. The display name is required and should be user-friendly so people recognize what it is. It also has to be unique in your domain.

    • Description: Use this box to describe the group so people know what the purpose of the group is. This description appears in the address book and in the Details pane in the new EAC.

    You can also select the group and then click Edit email address from the toolbar to change/edit the Primary email address, add/delete Aliases, and then click Save changes.

    Members

    Use this section to change/edit the following:

    • Under Members section, click View all and manage members to add/remove group members from the drop-down list and then click Save changes. The mail-enabled security group must have at least one member.

    Settings

    Under General settings section, select the checkbox Allow external senders to email this group if you want to allow the external users to send email to this group.

    Delivery management

    Use this section to manage who can send email to this group.

    • Sender options

      By default, only people inside your organization can send messages to this group. You can also allow people outside the organization to send messages to this group.

      • Only allow messages from people inside my organization: Select this option to allow only senders in your organization to send messages to the group. This means that if someone outside your organization sends an email message to this group, it is rejected. This is the default setting.

      • Allow messages from people inside and outside my organization: Select this option to allow anyone to send messages to the group.

    • Specified senders

      You can further limit who can send messages to the group by allowing only specific senders to send messages to this group. Select/remove one or more recipients/group from the drop-down list. If you add senders to this list, they are the only ones who can send mail to the group. Mail sent by anyone not in the list will be rejected.

      Important

      If you've configured the group to allow only senders inside your organization to send messages to the group, email sent from a mail contact is rejected, even if they're added to this list.

    Manage delegates

    Use this section to assign permissions to a user (called a delegate) to allow them to send messages as the group or send messages on behalf of the group. You can assign the following permissions:

    • Send As: This permission allows the delegate to send messages as the group. After this permission is assigned, the delegate has the option to add the group to the From line to indicate that the message was sent by the group.

    • Send on Behalf: This permission also allows a delegate to send messages on behalf of the group. After this permission is assigned, the delegate has the option to add the group to the From line. The message will appear to be sent by the group and will say that it was sent by the delegate on behalf of the group.

    To assign permissions to delegates in new EAC, add the delegates under the Edit delegates page, select the Permission type from the drop-down list and click Save changes.

    Message approval

    Use this section to set options for moderating the group. Moderators approve or reject messages sent to the group before they reach the group members.

    • Group moderators: To add/remove group moderators, search/add users from the drop-down list. If you've selected Require moderator approval for messages sent to this group and you don't select a moderator, messages to the group are sent to the group owners for approval.

    • Add senders who don't require message approval: To add/remove users that can bypass moderation for this group, search/add users from the drop-down list.

    • Notify a sender if their message isn't approved: Use this section to set how users are notified about message approval.

      • Only sender: This is the default setting. Notify all senders, inside and outside your organization, when their message isn't approved.

      • Only senders in your organization: When you select this option, only users or groups in your organization are notified when a message that they sent to the group isn't approved by a moderator.

    (Video) 10. Create Mail Enabled Security Group in Exchange 2019

Use the Classic EAC to create a mail-enabled security group

  1. In the Classic EAC, navigate to Recipients > Groups.

  2. Click New Manage mail-enabled security groups in Exchange Online (1) > Security group.

  3. On the New security group page, complete the following fields:

    • * Display name: Use this box to type the display name. This name appears in the shared address book, on the To: line when email is sent to this group, and in the Groups list in the Classic EAC. The display name is required and should be user-friendly so people recognize what it is. It also must be unique in the forest.

      Note

      If a group naming policy is applied, you must follow the naming constraints enforced for your organization. For more information, see Create a distribution group naming policy. If you want to override your organization's group naming policy, see Override the distribution group naming policy.

    • * Alias: Use this box to type the alias for the security group. The alias can't exceed 64 characters and must be unique in the forest. When a user types the alias on the To: line of an email message, it resolves to the group's display name.

    • Description: Use this box to describe the security group so people know what the purpose of the group is.

    • Organizational unit: You can select an organizational unit (OU) other than the default (which is the recipient scope). If the recipient scope is set to the forest, the default value is set to the Users container in the Active Directory domain that contains the computer on which the Classic EAC is running. If the recipient scope is set to a specific domain, the Users container in that domain is selected by default. If the recipient scope is set to a specific OU, that OU is selected by default.

      To select a different OU, click Browse. The dialog box displays all OUs in the forest that are within the specified scope. Select the desired OU, and then click OK.

    • * Owners: By default, the person who creates a group is the owner. All groups must have at least one owner. You can add owners by clicking Add.

    • Members: Use this section to add members and to specify whether approval is required for people to join or leave the group.

      Group owners don't have to be members of the group. Use Add group owners as members to add or remove the owners as members.

      To add members to the group, click Add Manage mail-enabled security groups in Exchange Online (2). When you've finished adding members, click OK to return to the New security group page.

      Select the Owner approval is required check box if you want the group owners to receive user requests to join the group. If you select this option, members can only be removed by the group owners.

  4. When you've finished, click Save to create the security group.

    Note

    By default, all new mail-enabled security groups require that all senders be authenticated. This prevents external senders from sending messages to mail-enabled security groups. To configure a mail-enabled security group to accept messages from all senders, you must modify the message delivery restriction settings for that group.

Use the Classic EAC to change mail-enabled security group properties

  1. In the Classic EAC, navigate to Recipients > Groups.

  2. In the list of groups, click the security group that you want to view or change, and then click Edit Manage mail-enabled security groups in Exchange Online (3).

  3. On the group properties page, click one of the following sections to view or change properties.

    When you're finished, click Save.

    General

    Use this section to view or change basic information about the group.

    • * Display name: This name appears in the address book, on the To: line when email is sent to this group, and in the Groups list. The display name is required and should be user-friendly so people recognize what it is. It also has to be unique in your domain.

    • * Alias: This is the portion of the email address that appears to the left of the at (@) symbol. If you change the alias, the primary SMTP address for the group will also be changed, and contain the new alias. Also, the email address with the previous alias will be kept as a proxy address for the group.

    • Description: Use this box to describe the group so people know what the purpose of the group is. This description appears in the address book and in the Details pane in the EAC.

    • Hide this group from address lists: Select this check box if you don't want users to see this group in the address book. If this check box is selected, a sender has to type the group's alias or email address on the To: or Cc: lines to send mail to the group.

      Tip

      Consider hiding security groups because they're typically used to assign permissions to group members and not to send email.

      (Video) Managing Mail-Enabled Security Group in Exchange Server 2016

    • Organizational unit: This read-only box displays the organizational unit (OU) that contains the security group. You have to use Active Directory Users and Computers to move the group to a different OU.

    Ownership

    Use this section to assign group owners. The group owner can add members to the group, and approve or reject requests to join the group. By default, the person who creates a group is the owner. All groups must have at least one owner.

If you select the Owner approval is required check box, the group owner or owners receive an email requesting approval to join the group. As previously mentioned, only owners can remove members from the group.

    Note

    This option will not work with mail-enabled security groups because of security-related limitations.

    Delivery management

    Use this section to manage who can send email to this group.

    • Only senders inside my organization: Select this option to allow only senders in your organization to send messages to the group. This means that if someone outside of your organization sends an email message to this group, it will be rejected. This is the default setting.

    • Senders inside and outside of my organization: Select this option to allow anyone to send messages to the group.

      You can further limit who can send messages to the group by allowing only specific senders to send messages to this group. Click Add Manage mail-enabled security groups in Exchange Online (8) and then select one or more recipients. If you add senders to this list, they are the only ones who can send mail to the group. Mail sent by anyone not in the list will be rejected.

      To remove a person or a group from the list, select them in the list and then click Remove Manage mail-enabled security groups in Exchange Online (9).

      Important

      If you've configured the group to allow only senders inside your organization to send messages to the group, email sent from a mail contact will be rejected, even if they're added to this list.

    Message approval

    Use this section to set options for moderating the group. Moderators approve or reject messages sent to the group before they reach the group members.

    • Messages sent to this group have to be approved by a moderator: This check box isn't selected by default. If you select this check box, incoming messages will be reviewed by the group moderators before delivery. Group moderators can approve or reject incoming messages.

    • Group moderators: To add group moderators, click Add Manage mail-enabled security groups in Exchange Online (10). To remove a moderator, select the moderator, and then click Remove Manage mail-enabled security groups in Exchange Online (11). If you've selected "Messages sent to this group have to be approved by a moderator" and you don't select a moderator, messages to the group will be sent to the group owners for approval.

    • Senders who don't require message approval: To add people or groups that can bypass moderation for this group, click Add Manage mail-enabled security groups in Exchange Online (12). To remove a person or a group, select the item, and then click Remove Manage mail-enabled security groups in Exchange Online (13).

    • Select moderation notifications: Use this section to set how users are notified about message approval.

      • Notify all senders when their messages aren't approved: This is the default setting. Senders inside and outside your organization will be notified when their messages aren't approved.

      • Notify senders in your organization when their messages aren't approved: When you select this option, only people or groups in your organization are notified when a message that they sent to the group isn't approved by a moderator.

      • Don't notify anyone when a message isn't approved: When you select this option, notifications aren't sent to message senders whose messages aren't approved by the group moderators.

    Email options

    Use this section to view or change the email addresses associated with the group. This includes the group's primary SMTP addresses and any associated proxy addresses. The primary SMTP address (also known as the reply address) is displayed in bold text in the address list, with the uppercase SMTP value in the Type column.

    • Add: Click Add Manage mail-enabled security groups in Exchange Online (14) to add a new email address for this mailbox. Select one of following address types:

    • Edit: To change an email address associated with the group, select it in the list, and then click Edit Manage mail-enabled security groups in Exchange Online (15).

      Note

    MailTip

    Use this section to add a MailTip to alert users of potential issues before they send a message to this group. A MailTip is text that's displayed in the InfoBar when this group is added to the To, Cc, or Bcc lines of a new email message. For example, you could add a MailTip to large groups to warn potential senders that their message will be sent to lots of people.

    Note

    MailTips can include HTML tags, but scripts aren't allowed. The length of a custom MailTip can't exceed 175 displayed characters. HTML tags aren't counted in the limit.

    Group delegation

    Use this section to assign permissions to a user (called a delegate) to allow them to send messages as the group or send messages on behalf of the group. You can assign the following permissions:

    • Send As: This permission allows the delegate to send messages as the group. After this permission is assigned, the delegate has the option to add the group to the From line to indicate that the message was sent by the group.

    • Send on Behalf: This permission also allows a delegate to send messages on behalf of the group. After this permission is assigned, the delegate has the option to add the group in the From line. The message will appear to be sent by the group and will say that it was sent by the delegate on behalf of the group.

    To assign permissions to delegates, click Add under the appropriate permission to display the Select Recipient page, which displays a list of all recipients in your Exchange organization that can be assigned the permission. Select the recipients you want, add them to the list, and then click OK.

Use PowerShell to manage mail-enabled security groups

Use Exchange Online PowerShell to create a mail-enabled security group

This example creates a security group with an alias fsadmin and the name File Server Managers. The security group is created in the default OU, and anyone can join this group with approval by the group owners.

New-DistributionGroup -Name "File Server Managers" -Alias fsadmin -Type security

For more information about using Exchange Online PowerShell to create mail-enabled security groups, see New-DistributionGroup.

How do you know this worked?

To verify that you've successfully created a mail-enabled security group, do one of the following:

  • In the new EAC, navigate to Recipients > Groups > Mail-enabled security. The new mail-enabled security group is displayed in the group list.

  • In the Classic EAC, navigate to Recipients > Groups. The new mail-enabled security group is displayed in the group list. Under Group Type, the type is Security group.

  • In Exchange Online PowerShell, run the following command to display information about the new mail-enabled security group.

    Get-DistributionGroup <Name> | Format-List Name,RecipientTypeDetails,PrimarySmtpAddress

Use Exchange Online PowerShell to change mail-enabled security group properties

Use the Get-DistributionGroup and Set-DistributionGroup cmdlets to view and change properties for security groups. Advantages of using Exchange Online PowerShell are the ability to change the properties that aren't available in the EAC and to change properties for multiple security groups. For information about which parameters correspond to which distribution group properties, see the following articles:

  • Get-DistributionGroup

  • Set-DistributionGroup

Here are some examples of using Exchange Online PowerShell to change security group properties.

This example displays a list of all security groups in the organization.

Get-DistributionGroup -ResultSize unlimited -Filter "RecipientTypeDetails -eq 'MailUniversalSecurityGroup'"

This example changes the primary SMTP address (also called the reply address) for the Seattle Administrators security group from admins@contoso.com to seattle.admins@contoso.com. The previous reply address will be kept as a proxy address.

Set-DistributionGroup "Seattle Employees" -EmailAddresses SMTP:sea.admins@contoso.com,smtp:admins@contoso.com

This example hides all security groups in the organization from the address book.

Get-DistributionGroup -ResultSize unlimited -Filter "RecipientTypeDetails -eq 'MailUniversalSecurityGroup'" | Set-DistributionGroup -HiddenFromAddressListsEnabled $true

How do you know this worked?

To verify that you've successfully changed properties for a security group, do the following:

  • In the new EAC, select the group to view the property or feature that you changed. Depending on the property that you changed, it might be displayed in the details pane for the selected group.

  • In the Classic EAC, select the group and then click Edit Manage mail-enabled security groups in Exchange Online (18) to view the property or feature that you changed. Depending on the property that you changed, it might be displayed in the Details pane for the selected group.

    (Video) Mail security in Exchange online

  • In Exchange Online PowerShell, use the Get-DistributionGroup cmdlet to verify the changes. One advantage of using Exchange Online PowerShell is that you can view multiple properties for multiple groups. In the example above where all security groups were hidden from the address book, run the following command to verify the new value.

    Get-DistributionGroup -ResultSize unlimited -Filter "RecipientTypeDetails -eq 'MailUniversalSecurityGroup'" | Format-List Name,HiddenFromAddressListsEnabled
