There is no native way to move mail back into Exchange from Archive Manager. However, you could use a product like Recovery Manager for Exchange or Migration Manager for Email Archives to move the mail from Archive Manager back into a mailbox.
I would recommend that you upgrade your version of Archive Manager to the current version prior to using either of the suggested tools for migrating the mail back as 4.7 is fairly old. Note, if you do choose this option you will have to upgrade to 4.8 first then to 5.3/5.4.
You can also use Search Exporter, to export mail to a PST but you will lose the folder structure when using this option.
