I work in a mid-sized business. We need a collaborative tool for improving our Office productivity. We have shorted down to Office 365.
Currently, we are looking at Office 365 Business Premium and Office 365 Business Essentials.
All we need is an Office suite and basic team co-ordination tools like either Yammer or Teams.
So, which one should I go for?

Waiting for your response.
Thanks in advance.

Regards.
