Allow a member to add email accounts and shared email adresses

[daansk99]

If I want to have an office 365 user, that has the possibility to add email users (buying licenses), add + remove users from shared email boxes. What permissions do I need to give that kind of user?

You will need to assign him to the "Mail Recipients" role in Exchange. By default this role is part of the Recipient Management role group, which you can find under the Exchange Admin Center -> Permissions -> Admin roles. If you want to use the Office 365 admin roles, the only one that has such permissions by default is the Global admin one. Try to avoid using this one :)
