One of a set of tools we're offering as a way of saying thank you for being a part of the community.
Export your entire mailbox into a *.pst file, then import that *.pst file into your new version of Outlook. This should recover and transfer everything into your new version. You could choose to keep your old files in the *.pst and just open it as an extra service as well. This is done thru Tools, Services, Add personal folder and point to that file so that the items remain separate, but still accessible.
Hope this helps.
