You can use the following scripts and bonus tips in any combination if the corresponding component exists in the repository for a specific user. After identifying the user with the appropriate attribute, you can proceed to remove all of their data from the repository. It’s essential to note that this data deletion process will not reduce the database’s size. Instead, data blocks associated with the user will be marked as white space and overwritten in subsequent job runs.

To initiate the process, you should launch PowerShell from within Veeam Backup for Microsoft Office 365. This action will automatically load the necessary toolkit to execute these commands.
