I’m helping with a Google Workspace migration where several users have Outlook PST archives. The biggest challenge is handling multiple files without manually repeating the same process for every user.

I’ve been researching ways to import PST to Google Workspace and found DRS PST to Gmail migration Tool . It supports loading multiple PST files and, after authentication, automatically displays the Google Workspace users so the administrator can choose the accounts that need data migrated.

The authentication process uses the Workspace Admin email along with a Service Account JSON key. That seems more suitable for an organization than having users individually handle every archive.

There are also filtering options, so the migration doesn’t necessarily have to include every message in a PST. I’m wondering how this compares with using Google’s standard migration utilities when dealing with a larger number of PST files.

If anyone has handled a multi-user PST-to-Workspace project, what approach worked best for you?
