Viva Engage vs. A dedicated intranet: What’s best for your people?

Most modern enterprises run on Microsoft. For secure document storage and high-classification data, SharePoint is the standard. But for organisations with huge frontline teams—like Aldi, NatWest, or Five Guys—SharePoint often hits a wall.

On paper, sticking with Viva Engage and SharePoint is the easy win. Your IT department already pays for the licences, the security sign-off is done, and it’s “right there.” It feels like the path of least resistance. Why add another platform when you can just toggle on a social layer?

But “available” doesn’t mean “effective.” While using existing tools saves on upfront software costs, it often creates a massive hidden tax: disengagement. If your frontline can’t log in easily, or your warehouse staff find the interface too noisy to navigate, the “free” tool becomes the most expensive investment you’ve ever made.

For office-based teams, SharePoint is a daily tool. For the frontline, it is a barrier. Relying solely on the Microsoft ecosystem often leaves your most critical workers in the dark for three reasons:

• Licensing costs: Handing out 50,000 full Microsoft 365 seats just so staff can check a rota or a policy isn’t a strategy. For most CFOs, it’s a non-starter.
• Access friction: SharePoint was built for desktops. On a personal mobile, the multiple layers of authentication are a headache. Frontline staff won’t battle a login screen during a busy shift.
• Overcrowded features: Organisations often try to force every SharePoint feature onto the frontline to justify the spend. The result? A cluttered interface that no one uses.

“Internal comms at scale often defaults to physical notice boards because there is no direct digital line to the employee. SharePoint doesn’t solve that; it only reaches the 5% in the office.” — David Ferguson, Chief Product & Technology Officer.

This is where the debate is won or lost. If your workers are in a warehouse, on a shop floor, or on the road, Viva Engage has a high barrier to entry. It usually requires a Microsoft 365 licence and a corporate email address.

We built Oak Engage to connect everyone, regardless of their role or location.

• No licence? No problem: Reach your frontline via a mobile app without the cost of a full M365 seat.
• Instant utility: Frontline workers don’t want a social feed to scroll. They need work tools. Payslips, rotas, and safety briefings should be in their pocket. Oak makes the intranet a tool, not a distraction

At first glance, Viva Engage and Oak look similar. Both have feeds, news, and profiles. But their DNA is different.

• Viva Engage is a social layer. It’s built for community, “Ask Me Anything” sessions, and bottom-up conversation. It’s where employees talk.
• A dedicated intranet is your single source of truth. It’s built for governance, structured knowledge, and targeted comms. It’s the place for anything and everything work-relate

Moving to a dedicated intranet doesn’t mean leaving Microsoft. Oak Engage works in tandem with SharePoint so you get the best of both worlds.

• Unified search: No more hunting through folders. One search pulls results from Oak and your SharePoint libraries simultaneously.
• Live document sync: Update a policy in SharePoint and it updates instantly in Oak. You keep Microsoft’s security with Oak’s user-friendliness.
• Targeted social: Viva Engage can feel like a shouting match. By using Oak as your gateway, you can highlight specific Viva communities to specific people—keeping the “social” relevant.
• Bridging the gap: Use Viva Connections to surface your Oak intranet directly inside Microsoft Teams. Your people get the structure of Oak without leaving the app they use for daily work.

The most successful organisations don’t migrate everything at once; they adopt a hybrid strategy.

Large organisations categorise data. High-classification documents stay in SharePoint—it’s the gold standard for security. But information for “public consumption”—company news, culture updates, and peer recognition—belongs on a platform like Oak.

Implementation: From 6 weeks to 48 hours

The biggest blocker for IC teams is the perceived “effort” of a new platform. While the industry standard is 6–8 weeks, technical deployment can be significantly faster.

Take Five Guys. They achieved a full frontline rollout across multiple countries in just 48 hours. Unlike SharePoint, which often requires external consultants, modern engagement apps are designed to be managed by a single IC professional.

Engagement isn’t “fluff.” To secure a budget, you have to map IC to outcomes:

• Retention: Engaged frontline workers stay longer, directly reducing recruitment costs.
• Culture: When a CEO and the staff member having conversations with customers every single day share the same platform, you build a unified culture that transcends borders.

Key Takeaways

• Don’t Ditch, Integrate: Keep high-security docs in SharePoint and use Oak as the engagement layer.
• Frontline First: Remove expensive licences and complex logins.
• Start Small: Launch a core version in as little as two weeks to solve immediate gaps.
• Empower IC: A platform that no one feels like they need to maintain, but can easily use and manage from IT to the Comms team.

The 2026 verdict: Don’t just connect, engage. Connecting people is easy. Engaging them is hard. While Viva Engage is great for a “chat,” it lacks the structure and mobile utility that complex frontline workforces need. By choosing a dedicated platform like Oak Engage, you’re creating a digital workspace that works just as hard as your people do.
