Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi JCarabott,
We can’t check the date when license is assigned or removed on a user with Office 365 Powershell.
However, you can check the date by Office 365 Security & Compliance Center
Please try following the steps:
Open portal.office.com->Admin centers->Security & Compliance->Search & investigation->Audit log search.
Regards,
Liam
