I am going to migrate onto Google Workspace. I will create several TeamDrives under there, where my contractors (photographer etc.) will upload the files they created.
They will use their own gmail account, not with an email of my company's domain.
In personal Google Drive, when someone shares a folder/file with me, those are still owned by them. Therefore, when they delete on their own personal account, those files are also removed from my side. As per my understanding, TeamDrive sorts out this issue. When they upload a file/folder into a TeamDrive using their own gmail account, the ownership of these are taken by the TeamDrive and protected from deletion in the future.
Can someone help me to clarify these questions?
Thanks
According to the documentation available about Shared Drives, which I think is the feature you are referring to, if a user outside of your organization contributes to your organization's shared drives, the content uploaded, created or edited is transferred to it and belongs to the shared drives uploaded.
The documentation says the following: "Any work an external user contributes (for example, edits to, creating, or uploading a file) is transferred to and owned by the domain that created the shared drive."
Here is the link in case you need it.
In addition, the external user shouldn't be able to remove the file unless the privilege given is Manager or Content Manager; to upload Contributor privilege is enough. Check the documentation about the access levels.
