Investing in a more reliable Microsoft Graph PowerShell experience

We’re focusing Microsoft Graph PowerShell on the platform where we can give you the most reliable, capable, and well-maintained experience: PowerShell 7.x and later. Built on modern .NET, PowerShell 7.x resolves many of the underlying assembly-loading and dependency issues that affect Windows PowerShell 5.x today. Concentrating our engineering there means faster fixes, quicker delivery of new features, and fewer platform-specific failures for you.

To make that focus possible, today we’re announcing that Windows PowerShell 5.x is entering a 12-month retirement period for the Microsoft Graph PowerShell modules. Over this period, we’ll wind down maintenance on 5.x and direct new investment, development, and validation to PowerShell 7.x and later. The v2.x modules will keep working on Windows PowerShell 5.1 throughout — this is a planned transition, not a switch we’re flipping today.

Retirement refers to maintenance, not compatibility. During the retirement period the v2.x modules will continue to declare compatibility with Windows PowerShell 5.1 and, in most cases, keep functioning in existing environments just as they do now. What changes is where our engineering effort goes: new features, bug fixes, and validation will target PowerShell 7.x, and issues specific to Windows PowerShell 5.x will no longer be actively investigated or fixed. 

Timeline

• Now through the next ~12 months (retirement period). The v2.x modules remain compatible with Windows PowerShell 5.1 and will receive security fixes as required. Maintenance for PowerShell 5.x compatibility winds down, while active development, validation, and investment move to PowerShell 7.x and later — giving you time to plan and complete your migration without disruption.
• In Q4 CY 2026 a new major version of Microsoft Graph PowerShell will be released. With the release of v3.0.0 no new versions of v2 will be published unless security fixes are required. V3.x modules will not have explicit support for Windows PowerShell 5.x and are only supported for PowerShell 7.x.

Call to Action

If you’re still on Windows PowerShell 5.1, begin planning your move to PowerShell 7.x now. It’s the recommended and only maintained platform going forward, and it delivers the more reliable experience described above.

We appreciate our customers’ partnership and understanding as we make this transition and continue investing in the future of Microsoft Graph PowerShell.
