We have Enterprise licenses available for the Service account and have more than enough licenses of the Academic equivalent (A3 instead of E3) which have the same features. P365 T2T is complaining about not having a license available. Is there anything we can do to overcome that situation?

Office 365 License Requirements: One available license (E1 minimum) for destination tenants.
Important Note: For the best application experience, it is always recommended to use the Global Administrator role. However, this account only requires the Global Administrator role during the initial Project setup, reconnections to the tenant, or during a Domain Cutover event, where more authority is required. All account and role management is strictly the responsibility of the tenant administrators.
