AD user offboarding GUI tool

User offboarding is a critical process in every organization, ensuring that the departure of employees is handled securely and efficiently. To streamline this process and minimize human errors, we'll create a powerful PowerShell tool that not only disables Active Directory (AD) accounts but also removes users from all security groups, moves them to a "Disabled Users" Organizational Unit (OU), and adds an exit date timestamp to their display names.

Let's break down the step-by-step process of how this PowerShell tool for user offboarding works:

Launch the application by either double-clicking it or executing the PowerShell script.

After launching the application, enter the username of the user you wish to offboard and then click on the "Search" button. A pop-up will appear displaying matching usernames for you to select from.

As you can observe in the image below, the application will collect essential user details such as Email, Reporting Manager, Last login, Display Name, and Account Status. These details will be prominently displayed within the application for your reference.

Once you have verified that this is indeed the user you wish to offboard, you can proceed by clicking on the "Disable" button to perform the offboarding process in Active Directory.

After the disable process is completed, a pop-up notification will inform you that the Active Directory account of the specified user has been disabled. Additionally, this notification message will be copied to your clipboard. During this process, the following actions will be performed:

  1. AD Account Disabled: The user's Active Directory account is disabled, ensuring that they can no longer access network resources.

  2. User Moved to Disabled User OU: The user will be transferred to the "Disabled User" Organizational Unit (OU) within Active Directory. This organizational unit is typically used to segregate disabled or offboarded users from the rest of the user accounts.

  3. Removal from Security Groups: The tool will remove the user from all security groups to prevent any unintended access or permissions that may have been associated with their account.

  4. Timestamp Added to Display Name: The current date is added as a timestamp to the user's display name, indicating when the offboarding process was executed. This can be helpful for record-keeping and tracking.

These actions help ensure a secure and well-documented offboarding process while minimizing the chances of errors or oversights.

Upon the completion of the offboarding process, comprehensive logs containing all the relevant details will be automatically generated and saved in a specific location for future reference. These logs will be stored in the directory:

C:\Users\Public

Having these logs readily available is invaluable for auditing, compliance, and record-keeping purposes. It provides transparency and accountability in the offboarding process, ensuring that all steps are executed correctly and in compliance with organizational policies and security protocols.

Here is the full PowerShell code for the tool:
