Hi @Anonymous
What is the 'xxxxx' part in the error message Resource 'xxxxxxxx' does not exist or one of its queried reference-property objects are not present.?
Is it the groupID of the Team or the user you would like to add to the Team?
If it is the user, please make sure you are using UPN for the user parameter.
Reference: Add-TeamUser
