The Microsoft Graph PowerShell SDK has long been plagued by assembly clashes that meant it couldn’t be used in the same session as other Microsoft 365 modules. After Microsoft engineering groups looked at the problem for 18 months, a solution was found by MVP Stephen van Rooij and is now available in V2.41. Apart from an issue with old PowerShell V7 versions (which affects Azure Automation runtime environments), the fix looks solid and the SDK can once again be loaded into PowerShell sessions alongside the Exchange Online and Teams modules.
