Hi Linda Wang,
Thank you for your promp response, but as I mention.. Commands does not exist on my end, which I am the Global Administrator. If you can see on the Screenshot, I already executed Get-Command Add* to show available commands for me. Please note, that I am already conneted to our Outlook server
So, I dont have this commands
Add-RecipientPermission
Add-MailboxPermission
