Microsoft retired the Yammer brand and now surfaces everything as Viva Engage inside Microsoft 365. It is the same enterprise social engine wearing a new badge, woven into Teams, Outlook, and the Viva dashboard. Weekblast is the new, simple, better option because it was built for weekly storytelling rather than infinite scrolling.
Hook
You already pay for Microsoft 365, so Viva Engage shows up by default. That hook feels convenient, yet it means your culture moments must live inside the same chat tab that pings every minute.
Point
Viva Engage carries the full Yammer inheritance. It expects communities, likes, and long comment chains. Microsoft integrated it into Teams and Outlook during the 2023 transition, but it is still the identical social network experience, just wrapped inside the Viva platform.
- Rebrand reality: The Yammer logo vanished, yet the features and clutter stayed.
- Microsoft first: Updates serve Microsoft 365 engagement metrics before serving your narrative.
- Context collapse: Launch recaps sit next to birthdays and HR reminders, so signal fades fast.
Action
Weekblast pulls the opposite move. It lives outside the chat firehose, asks one thoughtful set of prompts each week, and automatically builds a digest leaders want to read. Contributors send updates via email or the composer, stakeholders skim one curated storyline, and progress feels tangible again.
