WHERE M365 BREAKS DOWN
When your Microsoft 365 stack should be helping, not hurting
Most UK organisations buy E3 or E5 licences and then run them at 30% of their value. Security drifts, costs creep, and adoption flatlines. We fix that.
Licence sprawl and shelfware
✕
Unused E5 seats, duplicated add-ons, and the wrong SKU mix for your headcount quietly burn budget every month, and the audit finds nothing for finance to claw back later.
✓
Right-size SKUs, reclaim seats, and renegotiate at renewal so spend matches actual usage.
Security baselines that drift
✕
Conditional Access policies, MFA enforcement and Defender configuration drift from baseline within weeks of go-live, and nobody notices until an audit.
✓
Monthly hardening reviews against Microsoft Secure Score and CIS benchmarks, with drift remediated before audit.
Adoption flatlines after rollout
✕
Teams calls, SharePoint sites and Power Platform apps get deployed but never embedded. End-users default to email and shared drives, and adoption never materialises in numbers.
✓
Adoption sprints, role-based training, and Viva Insights tracking lift active usage past 80% within the first quarter.

Microsoft 365 Managed Services FAQ
What's included in Microsoft 365 Managed Services?
Our Microsoft 365 Managed Services cover end-to-end tenant operations: licence administration, user lifecycle, mailbox and SharePoint governance, Conditional Access and MFA enforcement, Defender for Office configuration, Intune device compliance, Purview DLP, adoption sprints, and quarterly licence audits. Everything sits under one fixed monthly per-seat fee. We’ve done this for UK firms like Team Savante who migrated 100+ mailboxes in a single weekend with zero disruption.
How quickly can you take over our existing Microsoft 365 tenant?
Transition takes 4-6 weeks end-to-end. Week 1-2 we audit your tenant against the Microsoft Secure Score baseline and produce a costed remediation plan you keep regardless of next steps. Weeks 3-4 we implement Conditional Access, MFA enforcement, Defender baselines and Intune profiles, aligned with Microsoft 365 admin guidance. Weeks 5-6 we cut over service desk, monitoring and admin without disrupting users. Read more in our guide to what 24/7 M365 support should actually mean.
Are you an authorised Microsoft Partner?
Yes. Transputec is a Microsoft Solutions Partner with Modern Work and Security designations, earned through validated UK customer outcomes (not just exam passes). We also hold ISO 27001 certification and have direct access to Microsoft FastTrack for complex migrations. See the full list of accreditations on the Why Transputec page.
How does your pricing work?
Fixed monthly per-seat fee covering admin, security reviews, adoption sprints, monitoring and on-call hours. No surprise change-control invoices. Quarterly licence audits typically save 15-25% on shelfware and SKU mis-fits, paying for the management fee multiple times over. We also align hardening reviews to UK guidance such as the NCSC Cloud Security collection and Cyber Essentials, so audit evidence is ready when you need it. Specific pricing depends on tenant size, security tier (E3 vs E5) and SLA requirements – the M365 health check covers all of it.
What happens if we want to leave?
30 days notice. You get a full runbook, credentials transfer, admin handover and all configuration documentation. We’ve been ISO 27001 certified since 2018, so the hand-back process is audit-ready. We aim to leave your tenant in better shape than we found it – even on exit.
Can you migrate us from Google Workspace to Microsoft 365?
Yes. We run wave-based migrations from Google Workspace to Microsoft 365 with named cutover plans and zero end-user downtime. Standard scope: mail and calendar from Gmail/Calendar to Exchange Online with read-only legacy archive, Drive content to SharePoint Online + OneDrive for Business with permission inheritance preserved, Docs/Sheets/Slides converted to Word/Excel/PowerPoint (or kept native if preferred), Meet to Teams with calendar federation. Most UK mid-market migrations land in 6 to 12 weeks end-to-end. See Microsoft enterprise migration documentation for the platform baseline.
