Hello, everyone! Since the beginning of this year, I've been using Google Admin Console, therefore, I've been gaining new skills, and I'd like to share all my new knowledge with all of you. Before adding users, make sure that there are available licenses, if not, you need to purchase more user licenses, you should take a look at this link posted by Google. On the other hand, how many users you need to add? This option is recommended for adding up to 150,000 users, if you need to update more than that, I recommend you use APIs.
