I’m trying to set a user as the Owner of various distribution groups, but not as a member. When I add them as an Owner, they are automatically added as a member. When I try to remove them as a member, I get an error message which is preventing me from doing this. “Only Members who are not owners can be removed from group.”
Office 365 provides the option to have Owners who are not members when creating a new distribution list, in the form of a checkbox that says “Add Group Owners as Members”. This checkbox is not available for existing distribution lists, only new distribution lists.
Is there a powershell command, or some other way to change this setting on an existing distribution list, so that I can have a user who is an Owner of a distribution list, but not a member?
