Limitations of using Graph PowerShell scripts to manage Microsoft Entra ID

While PowerShell provides powerful command-line capabilities for managing Microsoft Entra ID, it comes with several limitations that can make administration challenging:

• Requires administrators to have in-depth knowledge of PowerShell scripting.
• Lacks a graphical user interface (GUI), making it difficult to track and visualize configurations.
• Does not provide an easy way to delegate specific management tasks to different administrators.
• Error messages can be complex and lack clear troubleshooting guidance.
