2010 Exchange to office 365 migration without full access user

We are migrating a clients email from a hosted exchange 2010 provider to office 365.  The provider of exchange is telling us they can't give us a user with full access to all mailboxes. But they can change all the account passwords.  From what I can tell and what i've done in the past we probably can't use the office 365 migration wizard correct?   Is there any way to migrate each mail box with office 365 or another migration tool since we can change all the account passwords?

Local pst migrations are not an option.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I highly doubt the option to grant full access is not available, but if it really isnt, there's not much you can do apart from PST migration. There are also some 3rd party tools that work with EWS impersonation, so maybe this is an available option. You should really discuss this with the provider.
