TL;DR: Microsoft 365 offboarding failures can leave former employees able to access SharePoint, OneDrive, Teams, groups, and licenses after departure, creating data exposure and unnecessary cost, according to Zluri. The real governance issue is not just deprovisioning speed, but whether identity, data, and group membership are revoked as one lifecycle event.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “5 Best Practices for Office 365 Offboarding in 2026”.
Key questions
Q: What breaks when Microsoft 365 offboarding is incomplete?
A: Incomplete Microsoft 365 offboarding leaves former employees able to retain access through active sessions, inherited group membership, or shared collaboration spaces.
Q: Why do manual offboarding processes create compliance risk?
A: Manual offboarding often leaves gaps between the employee departure and the actual revocation of SaaS access.
Q: What are the signs that Microsoft 365 offboarding is failing?
A: Common signs include inactive users still appearing in Teams or groups, licences remaining assigned after termination, and data not being moved before account deletion.
Practitioner guidance
- Revoke all Microsoft 365 sessions at departure Terminate active sessions as part of the exit workflow so the account cannot continue to access collaboration data after the user leaves.
- Block sign-in before any downstream clean-up Disable the account or reset credentials immediately so old passwords cannot be reused while data and licence actions are still in progress.
- Move or preserve OneDrive content before account removal Transfer the departing user’s data to an approved location before deletion so business records are not lost when the account is retired.
Bottom line: Microsoft 365 offboarding fails when organisations treat account disablement as the end of the lifecycle instead of the beginning of verification.

Offboarding is a lifecycle control problem, not an account deletion problem: Microsoft 365 exposure persists when identity revocation, session termination, group removal, data handling, and licence reclamation are treated as separate workstreams. That separation creates a window in which a departed user can still receive data or retain visibility. The practitioner conclusion is that offboarding has to be governed as one atomic lifecycle event.
A few things that frame the scale:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should IAM teams govern Microsoft 365 offboarding across identity, data, and licences?
A: They should treat departure as one controlled lifecycle event with a single exit sequence and verification step. That means revoking access, preserving required data, removing collaboration membership, and reclaiming licences under one process owner so no control is left behind.
