    @SebN-5008

    Have a check on the Exchange online admin that you used. Mark sure it is contained in the “Migration” permission role.

    You could create a new permission group which contained the "Migration" permission, then add your admin account to this group:

    Please note: Exchange 2010 isn't supported now, if you want to create a hybrid with Exchange online. I would suggest you migrate mailboxes to Exchange 2016 first, then create hybrid with Exchange 2016.
