Bulk add new members
Without using Distribution list which is only able to be created by I.T. admin, Can you implement the same function you have when you bulk add students or teachers to OneNote Class Notebook?
This is where you write an email then a semi colon separating each email. (eg. firstname.lastname@example.org; email@example.com; Jenny@hotmail.com).
It does not make sense that bulk adding of members can not be done by the user (only Admin with DL) when the whole purpose of a 'Team' is to have more than one person in it.
