I am trying to remove meeting rooms from a dynamic distribution group in Exchange Online, but I am encountering an error message indicating insufficient privileges. Many organizations have encountered this issue, but I am having difficulty finding a clear solution. Can anyone suggest a solution for removing members from a dynamic distribution group in Exchange Online?

    Hi,

    Thanks for posting your question in the Microsoft Q&A forum.

    Here are two methods you can choose from depending on your situation.

    1.If you want to delete dynamic distribution group members through PowerShell, you must be an organization administrator or a member of the "Security Group Creation and Membership" role in the Exchange Admin Center.

    1. You can delete or changes the distribution group by adding ManagedBy to its own attribute.

    Connect to Exchange Online by using remote PowerShell, and run the following cmdlet in Powershell:

    Set-DistributionGroup <group> -ManagedBy @{Add="<value1>", "<value2>", …} -BypassSecurityGroupManagerCheck

    I am the global administrator and have access to the group. I am trying to remove members by using this commandlet:

    PS C:\WINDOWS\system32> Get-DynamicDistributionGroup -Identity "All - BE Employees"

    Remove-DistributionGroupMember -Identity All - BE Employees -Member BEGuitar@ABC.com

    I get this error

    Name ManagedBy


    All - BE Employees cschumacher

    Remove-DistributionGroupMember : A positional parameter cannot be found that accepts argument '-'.

    At line:2 char:1

    • Remove-DistributionGroupMember -Identity All - BE Employees -Member A ...
    • 
          + CategoryInfo          : InvalidArgument: (:) [Remove-DistributionGroupMember], ParameterBindingException
      
          + FullyQualifiedErrorId : PositionalParameterNotFound,Remove-DistributionGroupMember
      
      

    The name of the Distribution group has a hypen in the name and powershell doesn't like that. How do I get around this?
