Yammer By Microsoft: How to activate it without Office 365?

[HappyTomatoOwl]

I want to know how to activate Yammer WITHOUT office 365.

Help?

It's a Microsoft product now, they own it. I assume they'd want people to register under an Office 365 account so more people are using their services

Yeah But, since its for educational use, it says i can be provided it without Office 365 activation.
That's what support said but they said i have to actually call Yammer Support for how to do it.
My phone doesn't work.
