Data Lifecycle Management (Retention)

Implement defensible retention across Microsoft 365 with clear governance, phased rollout, and operational control.

Microsoft Purview retention helps organisations control how long content is kept and what happens when it reaches the end of its lifecycle. You can apply retention settings broadly using retention policies (location-level), and more precisely at item level using retention labels. These controls help you meet regulatory obligations, reduce risk, and maintain a defensible information governance posture across Microsoft 365 workloads.

LW IT Solutions designs and delivers a practical retention programme that works in production. We translate your retention schedule and regulatory obligations into an implementable model of retention policies and retention labels, then roll out in phases to minimise disruption. We also implement ownership, change control, and reporting so retention remains defensible as your business processes and Microsoft 365 capabilities evolve.

Talk through your requirements and leave with a clear next-step plan.

Service Overview

Highlights

Retention architecture: when to use retention policies vs retention labels and how they interact
Retention policy design for Microsoft 365 locations (mailboxes, sites, OneDrive accounts, Teams-related locations where applicable)
Retention label taxonomy, naming standards, and user guidance aligned to your retention schedule
Label publishing and scoped rollout (users, groups, sites, administrative units where appropriate)
End-of-retention actions (delete, relabel, deactivate label, disposition review depending on configuration)
Operationalisation: ownership model, change control, documentation, and ongoing tuning cadence

Business Benefits

Reduce compliance risk by implementing consistent, documented retention controls across Microsoft 365
Reduce information sprawl through defensible disposal where appropriate
Improve audit readiness by demonstrating controlled retention settings and operational governance
Minimise disruption with phased rollout and clear end-user guidance

Typical use cases

Implement a baseline retention policy set for core workloads (Exchange, SharePoint, OneDrive, Teams-related locations)
Operationalise a retention label strategy for business records and high-risk content categories
Reduce data sprawl by applying end-of-retention deletion where appropriate, with governance and evidence
Align retention to eDiscovery/investigations so hold and preservation processes work predictably

How It Works

Discovery and schedule mapping - confirm drivers, in-scope workloads, and your retention schedule; define success criteria.
Design - define taxonomy, naming standards, and the policy/label model; design rollout and user guidance.
Build and pilot - implement policies/labels for a controlled scope; validate behaviour and user experience; refine.
Scale - expand deployment in phases; implement governance cadence and reporting.
Operate - support ongoing tuning, new labels/policies, and governance improvements.

Engagement Options

Baseline Retention - core retention policies for Exchange, SharePoint, OneDrive, and Teams-related locations
Label Strategy - design and rollout of retention labels for records and high-risk content
Phased Rollout - pilot-first deployment with staged expansion and user guidance
Operate - ongoing retention governance, change control, and optimisation support
