Palm Treo no longer syncs with Outlook 2007 calendar

Question

Foolishly I upgarded to Office 2010 not realising that my Palm won't sync with Outlook 2010. I reverted back to Office 2007 but now my Treo won't sync with the calendar. All else appears okay. I get the following message:
This handheld is associated with a differentprofile. To synchronize with that profile, close Outlook and synchronize again. To use this device with current Outlook profile, open the Hotsync custom dialogue and change the conduit settings to use this Outlook profile. See the Oultlook conduit help for details.
The conduit settings only allow me to change which over-writes which - computer or Treo. When I chnage to get the computer to over-write (as this is where my up-to-date info is, the same message appears. I going to get an iPhone soon if I can't get help. This is crazy.
Someone out there help...please.

If I understand correctly, then the old Outlook 2003 is no longer available to you. If that's the case, then all of your information should have been taken from your local outlook 2003 and put into the new outlook 2007 exchange. The only way you can sync with exchange is by using EAS. You will need the server address, domain name, and the username/password you use to log into outlook. I expect you may not have some of this information, which is where your IT department will be able to fill in the blanks. You won't need to use the Treo for email, but now that outlook 2003 is gone, that isn't an option for your contacts/calendar/notes anymore. When setting up the EAS on your device, it will ask what you want to sync, and you can select/deselect the options you prefer.
Hope this clarifies things a little bit.
