Since early December all of our Outlook365 users (in all tenants) have been getting the tag [External] in the subject line of their Outlook, and want it removed. I am only finding PS scripts which do not work. I have searched the settings and security areas of the admin console but have not found anything. Please help!

    I guess I am out of ammo on this one. We are a direct Microsoft CSP, and it worked for us. It might be that your reseller is not giving full tenant access??

    No. This is server settings. Registry only affects client settings.
