Hi. Exchange 2016 on-premise.

I have Security Group, i need remove 1 member and 1 member i need add.

After this command i got error:

Set-DistributionGroup "MyGroup" -ManagedBy @{Add='a.mihalevskiy'} -BypassSecurityGroupManagerC

Members can't remove themselves from security groups. Please set the group to Closed for requests to leave.

Ok, i fixed with command: Set-DistributionGroup "MyGroup" -MemberDepartRestriction:closed

But i can't return 'open'

[PS] C:\Windows\system32>Set-DistributionGroup "MyGroup" -MemberDepartRestriction:Open

Members can't remove themselves from security groups. Please set the group to Closed for requests to leave.

    Hi, @Андрей Михалевский

    Based on your description, I understand that you failed to set the property parameters.

    1.Did you successfully add members? Based on the command you provided, I successfully added myself to the security group. It is just that the command adds myself as the owner of the security group. I do not include myself in the membership.

    2.Are you removing yourself from the security group owner, or from membership? What are the commands you use to remove a user?

    3.In addition, for parameter -MemberDepartRestriction, Closed is the default value of the universal security group, and the Open value cannot be used in the universall security group. Details can be found here Set-DistributionGroup (ExchangePowerShell) | Microsoft Learn

    4.If you want to remove a user from a membership, you can use the command Remove-DistributionGroupMember -Identity "MyGroup" -Member. You can also implement the addition and removal of users in the EAC, but this requires you to have certain permissions, i.e. you are the owner of the group.
