  1. Download the Public Folder migration script from Microsoft’s official site.
  2. After that, you have to save the script file to a local folder on your system.
  3. Then, you need to place all required scripts in the same directory.
  4. Now, you have to download the Mail-Enabled Public Folder sync script.
  5. Next, save the SourceSideValidation.ps1 file in the same location.
  6. Afterwards, as an administrator, run the validation script in PowerShell 
  7. Now, you have to fix any errors shown in the validation report.
  8. Next, you have to check for duplicate or damaged public folders.
