Question : Adding Exchange to an existing POP in Outlook

If you view the original thread, we have users in remote offices who have gotten their email (POP) from yahoo for several years.  We are migrating them onto our Corporate Exchange server now.  I am working with Daniel (the original poster) on this issue.

Basically all we are trying to do is be able to give the users access to their old emails once they are getting all of their new email off of our Exchange server.  If all of the emails are getting downloaded from Yahoo's POP account onto each user's PC via Outlook now, why can't we just create a new account for Exchange, then leave the old POP emails as they are, but set that account to never send or receive new email, basically disabling the old Yahoo POP account?  

What if we then (after adding the Exchange account) delete the old POP account, will we still have access to the old emails or will they also be deleted with the POP account or otherwise unreachable?

Or maybe we archive them?  Would that allow them to be stored on the local users' PC and still give the user access to the emails for future reference?

The main thing is just allowing them to be able to access their old emails, so they need to show up in Outlook as well as their new emails from Exchange.  We are trying hard NOT to have to touch each users PST file and do an export then import back into Exchange.  I also don't want to drag-n-drop the old emails into the new folder structure that the Exchange account will create because I don't wan their old emails stored on the server (15krpm fiber EMC disk array) because that storage is expensive.

Answer : Adding Exchange to an existing POP in Outlook

I would suggest adding the Exchange account and remove the POP account, as you said. The POP account will have all the mail downloaded to a .pst file (typically located in C:\Documents and Settings\*username*\Local Settings\Application Data\Microsoft\Outlook) which you can then just use as an 'Archive Folder' in Outlook along with the Exchange account (which will be a .ost file if you use Cached Exchange Mode).

The benefit of doing it this way will be that when the user scrolls thru their old mail in the Archive Folders (from the POP account) and they reply to an email there, it will be sent from the Exchange account.
