I need your help answering the following:
1- Can I have in one plan two kinds of plans (E1 & E3)?
2- If I purchase 100 users, and then I delete 10 users, what will happen for the money which is related to the 10 deleted users?
3- What the meaning of choosing what exactly the office 365 users can use? In another word, I saw that I can select or unselect “office professional” or “Lync” license for users, for what I can use this?
