Tim_Banting right on. While I understand that VE and Yammer are one and the same, this move just leaves a lot of unanswered questions on the table.
One product, multiple names within the same ecosystem: Yammer, Communities, and Viva Engage.
I understand that the "Communities" name is going away in favor of VE. Personally, I never understood why it wasn't just called Yammer in the first place.
That is why I theorized that "Viva Engage" will eventually replace the name "Yammer" everywhere in M365. Not an easy task, but this is one of many steps in that direction.
However, the name change isn't what bothered me about this. I think what bothers me is that pivoting Yammer into Viva doesn't add any value for the customer. The features they announced this week could have easily been simple Yammer announcements.
