Automation of Microsoft Copilot License ManagementPHARMACEUTICALS INDUSTRYFebruary 2026 - February 2026Design and development of an automation solution for Microsoft Copilot 365 license management
Complete lifecycle automation of 1,000 Microsoft Copilot 365 licenses for Ipsen (pharmaceutical industry, ~30,000 employees). Result: ~30% weekly work time saved for the CloudOps team.What I delivered:- Main PowerShell script of 2,176 lines orchestrating 9 phases: usage data collection via Microsoft Graph API, identification of underutilizers, automatic license removal and assignment, SharePoint update, bilingual email notifications (FR+EN), and CSV reporting.
- Integration of the aiInteractionHistory API (GA 2025) to measure actual active days per user with a more precise metric than the Microsoft Admin Center, which only counts Copilot Chat.
- Parallel processing (ForEach-Object -Parallel, 15 threads) allowing evaluation of ~1,000 users in 6 minutes via the Graph API.
- Dynamically self-adjusting threshold to never release more licenses than the waitlist can absorb.
- Protections and safeguards: WhatIf simulation mode, 90-day grace period, GLT (VIPs) exclusion, manual override, automatic waitlist reconciliation.
- 5 additional scripts: CSV import, UUID resolution, test list cloning, one-click setup.
- 6 Azure DevOps YAML pipelines: weekly cron and manual trigger.
- Complete documentation: operational guide (576 lines) and technical specification (720 lines).
