Microsoft’s productivity stack is simpler to manage than ever—but its naming conventions remain anything but. Between Office 365, Microsoft 365 Apps, Microsoft 365 Copilot app, Business and Enterprise plans, even veteran IT leaders can get caught in terminology tangles.

This post gives you a clean mental model to brief leadership, reduce licensing confusion, and steer procurement conversations confidently.

The Key Insight: Microsoft Uses Three Naming Layers

When people say “Office,” they might be referring to one of three different things:

  1. Apps (Workloads) – Word, Excel, PowerPoint, Outlook, and friends.
  2. License SKUs – e.g., Microsoft 365 Apps for enterprise vs for business, or bundles like E3/E5 and Business Premium.
  3. Experience Hub – the new Microsoft 365 Copilot app (the web/mobile/Windows launcher).

Most confusion happens when these layers get mixed in the same conversation—especially with executives or procurement.

Layer 1: “Microsoft 365 Apps” = The Productivity Workload

This name refers to the familiar app set: Word, Excel, PowerPoint, Outlook, OneNote, and on Windows, Access and Publisher.
Think of it as the workload layer.

What it implies:

  • Access to desktop, web, and mobile versions (based on license).
  • Continuous updates through subscription—not a one-time purchase.

Layer 2: License SKUs = Who It’s For and What You Get

Both Microsoft 365 Apps for business and Microsoft 365 Apps for enterprise deliver the same core apps but differ in target audience and administrative flexibility.

  • For Business (SMBs): Simplified packaging, ideal for smaller orgs that want just the installed apps without full suite services. Often replaced by Business Premium, which includes apps + identity/security features.
  • For Enterprise: Designed for complex environments or larger orgs needing advanced deployment, shared devices, or phased transitions. Same apps—different management and compliance options.

In short: same apps, different licensing intent.

Where Suite Bundles Fit: “Apps + Services”

Many orgs don’t buy standalone Apps SKUs—they buy bundles that include them:

  • Microsoft 365 Business Premium
  • Microsoft 365 E3
  • Microsoft 365 E5

These bundles package the apps alongside collaboration, identity, and security services.
Rule of thumb:

  • “Apps SKUs” = license for apps only
  • “Suite bundles” = broader capability stacks (apps + services)

Layer 3: “Microsoft 365 Copilot App” = The Hub Experience

This is where the “Office was renamed” confusion comes from.
Microsoft renamed the Microsoft 365 app (formerly “Office” app) to the Microsoft 365 Copilot app.

It’s not a license—it’s an experience hub, the place where users can:

  • Launch apps
  • Find or share files
  • Access Copilot features (where licensed)

Clarify this internally:

The Microsoft 365 Copilot app is not a replacement license for Office—it’s the launcher hub.

A Clean Mental Model for Leadership

LayerNameMeaning
WorkloadMicrosoft 365 AppsThe core productivity apps (Word, Excel, etc.)
License SKUfor business / for enterpriseDefines who it’s for and what deployment rights apply
Experience HubMicrosoft 365 Copilot appThe web/mobile launcher—an interface, not a license

Quick 20-second script:

“Microsoft 365 Apps are the productivity tools. We license them as Apps for business or Apps for enterprise depending on our needs. The Microsoft 365 Copilot app is just the hub—it’s not a new license.”

Procurement Guardrails

  1. Separate “apps-only” from “bundle” decisions.
    Start from business outcomes, not app names. If you need collaboration or security, begin with Business Premium, E3, or E5.
  2. Stop using “Office” in procurement documents.
    It’s not a SKU anymore and can cause contract confusion. Use “Microsoft 365 Apps” with the precise SKU name.
  3. Treat “Copilot” as a feature add-on, not a naming term.
    Licensing for Copilot features is distinct from how “Apps” are named.

Standardize These Internal Terms

  • Microsoft 365 Apps = Productivity app set
  • Microsoft 365 Apps for business = SMB-focused apps-only SKU
  • Microsoft 365 Apps for enterprise = Enterprise-focused apps-only SKU
  • Microsoft 365 Copilot app = Hub/launcher experience
