What Viva Engage Actually Is and Whether Your Team Needs It

Someone in your organization probably asked "what's this Viva Engage app that showed up in Teams" recently. It used to be called Yammer, and Microsoft renamed it a few years back as part of folding it into the broader Viva suite. If you've been ignoring the icon in your Teams sidebar, here's what it actually does and when it's worth turning on.

What it's for

Viva Engage is built for open, company-wide conversation, not project work. Think of it as the difference between a Teams channel for your five-person project and a place where anyone in the company can ask "does anyone know who owns the printer contract" or post a photo from the holiday party. Teams channels are scoped to a team or department. Viva Engage communities are open by default and searchable by anyone in the tenant, which is exactly the point.

If your organization already has good habits around Teams channels for real work, Viva Engage is where the social and cross-department stuff goes instead of cluttering those channels. Leadership updates, all-hands recordings, "ask me anything" threads, these fit here better than in a Teams channel.

Is it worth turning on

For a five or ten person company, probably not. You already talk to everyone directly, and a Yammer-style feed just becomes another thing nobody checks. It starts to earn its place once you have enough people that employees genuinely don't know each other, several offices, or a leadership team that wants a way to post updates without spamming every channel or sending another company-wide email.

If you do turn it on, don't let it default to a storefront with no active communities. Create two or three communities with a clear purpose, an all-company one, maybe one per office or department, and get a couple of leaders posting regularly before you announce it to everyone else. An empty Viva Engage tab is worse than no Viva Engage tab, because it tells people the tool is dead on arrival.

One setting worth checking early: admins can control whether all employees can create new communities or whether that's locked down to a smaller group. Left wide open, you'll end up with a dozen near-duplicate communities within a month.
