That's basically caused by your first step, removing the license. Here's a quote from a recent article on the subject:

 

For example, one of the more common methods in the past was to disconnect the Exchange Online mailbox by removing the license, migrate the on-premises mailbox, then perform a restore (New-MailboxRestoreRequest) of the previous Exchange Online mailbox into the newly migrated mailbox. The main reason that we do not suggest this as a recovery method is that recovery from Exchange Online disconnected mailboxes cannot always be guaranteed (there can be factors like passing of time etc. which can make the process not be successful). If 99% of the time, it will work flawlessly, but that 1% of the time it doesn’t work, we do not suggest it because you might lose data as a result.

In any case, if you need the data preserved, make a backup copy to a PST file.
