Lots of news has emerged from Microsoft recently regarding the deprecation of the Azure AD PowerShell module and the older MSOL module. Although dates have slipped from the original June 30, 2022 deadline, the signs are that Microsoft will retire the modules in early 2023. However, the Azure AD and MSOL license management cmdlets will stop working on August 26, 2022, so that’s the immediate priority for script upgrades.
Anyone writing PowerShell code against Azure Active Directory probably uses the Azure AD module. In June 2022, Microsoft will deprecate the API underpinning the Azure AD module. Tenants who want to use PowerShell to create scripts to automate administrative processes will need to move to Graph API calls or use the Microsoft Graph PowerShell SDK. Either way, there’s a bunch of work to do to upgrade scripts.
