we are planning to buy O365 E3 licenses in batches. Instead of buying all licenses at a time. So my question is for example. If we are 10,000 employees company and to start if we have only 5000 O365 licenses. Can still all 10,000 access Yammer? As we want to rollout yammer first and want all the users to access yammer.
1. If yes I have also read that yammer is getting integrated with O365 Groups than how does the licensing work.
Likely a question for your Microsoft account team but my understanding with Yammer is it is now licensed by user and is no longer offered as a standalone SKU. So in the Office 365 admin portal every Yammer user would need a license assigned. Good luck. Eager to hear how it goes for you.
