Connect-AzureAD and Get-AzureADUser stopped working

Microsoft retired the AzureAD PowerShell module in 2025, after the MSOnline module. Scripts using Connect-AzureAD, Get-AzureADUser or Add-AzureADGroupMember need to move to the Microsoft Entra PowerShell module or the Microsoft Graph PowerShell SDK. Microsoft reports high cmdlet parity between AzureAD and Entra PowerShell, which makes the rewrite faster.

Fix it now

  1. Search every identity script and scheduled task for AzureAD.
  2. Use Microsoft's cmdlet migration map to find each Graph or Entra PowerShell equivalent.
  3. Register an app with the minimum Graph permissions; authenticate with a certificate or managed identity.
  4. Test against a pilot OU before re-enabling the scheduled task.
  5. Log every run and alert on failure.

Why this keeps happening

The AzureAD module replaced MSOnline in many scripts, and then it was retired too. Each rewrite that stopped at the next module is a script that will break again. See the full Microsoft Deadline Calendar.

Questions

Graph SDK or Entra PowerShell: which one?
Entra PowerShell is closer to the old AzureAD cmdlets and easier for existing scripts. The Graph SDK covers more of Microsoft 365. Either is supported.
