Best Practices for Preserving Data While Removing Microsoft 365 Users

• Offboarding employees is not an IT task; it’s a governance and risk event affecting organizational security, data compliance, and business continuity.
• Consistent offboarding protocols reduce security and data‑handling risks across M365 services, and automation reduces human error and compliance risks.
• Retention can drive storage charges for unlicensed OneDrive accounts.
• Unmanaged devices, orphaned workflows, and external sharing links can lead to data leaks, compliance issues, and business disruptions after a user leaves.

Employee offboarding affects security, regulatory compliance, and Microsoft 365 costs. A former user’s access should be removed quickly while preserving data through retention controls, rather than by keeping the account or license active. How an organization manages retention, ownership, and automation determines whether a business reduces risk and cost or creates compliance gaps, vulnerabilities, and data loss.

In this report, “license” refers to the user’s M365 license and “account” is the user’s Entra ID account.
