Figure out how to stop it from running!!!
I removed this from Chrome months ago. Every night it still runs. No one will answer how to stop it.
How does it even have access to keep running?!
I re-installed the app, then opened it by going to chrome://apps then clicking on Drive Migrator.
I re-enabled the permissions and it took me to a page where I saw that it was still running the process. There was a convenient "stop process" button right there. Clicked that and it was fixed.
It's upsetting that it was this complex to resolve the issue, but here it is for anyone else who needs help.
This is a nightmare, non stop emails. It won't go away. Please flag and get this plugin banned from the Chrome webstore.
We have the same issue, I've remove the app and still everyday it sends a status update saying it is unauthorized to run.

Try to unauthorise the app : https://security.google.com/settings/security/permissions
