調査の方向性

まず、Import-Module ExchangeOnlineManagement と Import-Module Microsoft.Graph によるロード順序の問題を再現し、次に、一覧にある PowerShell バージョンで WAM を有効にして Connect-ExchangeOnline と Connect-MgGraph をテストします。関連する issue #3254 と #3331、および既存の議論を確認して、意図された互換性の動作を判断します。両方のモジュールが 1 つのプロセス内で認証できるか、または競合によって文書化された決定論的なエラーが発生すれば完了です。

説明

Needs: Attention :wave: status:waiting-for-technical-design-work type:bug

Describe the bug

When both ExchangeOnlineManagement and Microsoft Graph PowerShell SDK are loaded in the same PowerShell session, interactive authentication fails consistently. Whichever module loads second fails with MSAL RuntimeBroker NullReferenceException or MissingMethodException. Each module works independently.

Environment

PowerShell: Windows PowerShell 5.1 and PowerShell 7.x (both affected)
ExchangeOnlineManagement: 3.8.x – 3.9.2
Microsoft.Graph PowerShell: 2.26+ (also confirmed with 2.34+)
OS: Windows 10 / 11
Auth: Interactive (WAM enabled by default)

Expected behavior

Both modules should be able to authenticate in the same process, or at minimum fail with a documented, deterministic error.

How to reproduce

Import-Module ExchangeOnlineManagement
Import-Module Microsoft.Graph

Connect-ExchangeOnline   # FAILS if 2nd
# or
Connect-MgGraph          # FAILS if 2nd

Reversing the import order reverses which module fails.

SDK Version

2.36.1

Latest version known to work for scenario above?

<2.26 (I think)

Known Workarounds

The only workaround I've found is to execute commands for one of these modules in a separate Powershell session
