Missing Mail on AOL after downloading Outlook 2007

I need help badly! I downloaded a Trial version of Office from Microsoft to try Outlook 2007 with my Palm Treo 755p. After I downloaded and set up the Outlook program and synced to my Palm to use Outlook in place of palm OS, I noticed that my current and old mail have disappeared from my AOL account completely. I work with those files every day and need them badly. I called AOL and they told me they cannot help me with the issue since it is a Microsoft problem and Microsoft tells me they do not support Trail software. I’m stuck! Can anyone shed some light on this problem to help me resolve it and get my AOL mail back where it belongs? Thanks Barry
