Update-DistributionGroupMember

The BypassSecurityGroupManagerCheck switch specifies whether to allow a user who isn't an owner of the group to modify or delete the group. You don't need to specify a value with this switch.

If you aren't defined in the ManagedBy property of the group, you need to use this switch in commands that modify or delete the group. To use this switch, your account requires specific permissions based on the group type:

• Distribution groups or mail-enabled security groups: You need to be a member of the Organization Management role group or have the Security Group Creation and Membership role assigned.
• Role groups: You need to be a member of the Organization Management role group or have the Role Management role assigned.

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

• Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
• Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

This parameter is available only in on-premises Exchange.

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

The Identity parameter specifies the distribution group or mail-enabled security group that you want to modify. You can use any value that uniquely identifies the group. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Email address
• GUID

The Members parameter specifies the recipients (mail-enabled objects) that will replace the current group members. You can use any value that uniquely identifies the recipient. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Email address
• GUID

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

Although it isn't required, it's a good idea to add only security principals (for example, mailboxes and mail users with user accounts or other mail-enabled security groups) to mail-enabled security groups. If you assign permissions to a mail-enabled security group, any members that aren't security principals (for example, mail contacts or distribution groups) won't have the permissions assigned.

The maximum number of entries for this parameter is 10000.

The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
