Add Member to Mail Enabled Security Group via PowerShell

Shiv bhushan Tomar 1 Reputation point

I am using PowerShell script to add memebr in an Mail Enabled security group:
after connecting to ExchangeOnlineManagement, using the below script to add member which is working fine for Distribution list but for Mail Enabled Security Group it throws an exception:

exception: "System.Management.Automation.RemoteException: You don't have sufficient permissions. This operation can only be performed by a manager of the group."

and If I add the parameter "-BypassSecurityGroupManagerCheck" it throws an exception :

exception: "Parameter -BypassSecurityGroupManagerCheck doest not match."


$group = Get-DistributionGroup -Identity $groupName

if($null -ne $group)
    Add-DistributionGroupMember -Identity $groupName -Member $userEmail -Confirm:$false

    Hi @Shiv bhushan Tomar

    The cause of this issue may be the account you are using to run the script doesn't have the required permission.

    If this account isn't the owner of the security group, in order to use the parameter BypassSecurityGroupManagerCheck to add members to this security group, the account must be assigned Security Group Creation and Membership role.
