Hi, Russ.
As Isaac said, the databases are very different. A thousand emails would be
stored in OE as a single .dbx file. In Vista, they are stored as 1,000
single-message .eml files. No way to share them.
Some of us have been able to share mail stores between Vista x86 and Vista
x64, but it's not a simple exercise.
When I was using both WinXP and Vista (mostly during the beta), I set both
OE and WM to "Leave a copy of messages on server". Then I decided which
would be my permanent archive going forward and set the other one to "Remove
from server after 5 days". I still had to store copies in both databases,
but they did not build up on the server indefinitely. And, when I settled
on Vista as my permanent OS, I could simply delete the WinXP database -
EXCEPT for Sent Items. Those are in only the database from which they were
sent, so I had to Import those from OE to Vista before deleting the Sent
Items folder in OE.
