This case study describes how a manufacturer consolidates onto its Microsoft 365 bundle, removing duplicate collaboration and content tools it had been buying separately. It is an anonymised composite drawn from common engagements, not a single named client. The figures are illustrative of the pattern rather than a specific account, and the company is not identified.
As an independent, buyer side advisor with no vendor relationship and no commission, we worked only for the buyer here. The engagement sits within the wider digital workplace cost optimization effort and drew on our collaboration tool rationalization service.
Situation
The organisation was a manufacturer of roughly 1,400 employees across several sites, with a lean IT team and a collaboration stack that had grown without a plan. It licensed Microsoft 365 E3 across most of the workforce, which already included Teams, SharePoint, and OneDrive. Alongside that, it paid separately for a video meeting tool, a messaging tool adopted by one division, and a content sharing platform bought years earlier. Each contract renewed on its own date and no one had ever looked at the total.
The overspend found
The review compared what the manufacturer paid for against what it already owned and actually used. The findings were familiar. The separate video tool duplicated Teams meetings, which were already paid for in E3. The messaging tool was used by a single division and overlapped Teams chat. The content platform held a modest amount of data that SharePoint and OneDrive could hold at no extra licence cost. Usage data showed adoption of the duplicate tools was low outside a few pockets. In short, the manufacturer was paying three separate bills for capability sitting unused inside a bundle it already bought.
| Tool | Overlap with Microsoft 365 | Actual adoption |
|---|---|---|
| Separate video meetings | Teams meetings, already in E3 | Low and declining |
| Division messaging tool | Teams chat, already in E3 | One division only |
| Content sharing platform | SharePoint and OneDrive | Modest, migratable |
Approach: how the manufacturer consolidates onto Microsoft 365 bundle
The work followed a sequenced roadmap rather than a single cut. First, we built the inventory and confirmed what E3 already included, anchored to Microsoft 365 plan documentation as of June 2026 (source: microsoft.com Microsoft 365 plan pages, as of June 2026). Second, we mapped each separate tool to its Microsoft 365 equivalent and pulled usage to size the real dependency. Third, we sequenced the retirements against renewal dates so nothing was paid for after it was switched off. Fourth, we ran a light change plan for the affected division, showing users the Teams equivalent before their tool was retired. The order mattered as much as the decision.
Outcome
Over a single renewal cycle the manufacturer retired all three separate contracts and moved the work onto Microsoft 365 capability it already owned. The duplicate video and messaging tools were dropped at their renewal dates, removing the whole of each recurring line. The content platform was migrated to SharePoint and OneDrive and its contract closed. The result was a material annual reduction in collaboration and content spend, with no loss of capability, because every retired function had an owned equivalent. Seats were also tidied during the move, removing a number of inactive licences. The saving recurs each year the retired contracts would otherwise have renewed.
Lessons for buyers
Three lessons stand out. First, the cheapest collaboration tool is usually the one already inside a bundle you buy, so confirm what Microsoft 365 includes before paying for anything separate. Second, sequence retirements against renewal dates so you never pay for a switched off tool, the same discipline behind a professional services firm cutting its DocuSign overage. Third, treat consolidation as change management, not just licensing, because moving capability rather than removing it is what keeps users with you. The overlap was quiet, but once mapped, the saving was straightforward.
