You are correct, journaling will not pick up old items.
To my knowledge, there is no easy way of doing what you want.
The only thing I could image is:
- Enable the user with a policy to archive everything > 1 Year, delete shortcuts. (and unlimited or desired retention)
- Disable the user
- Enable the user and assign him a NEW archive
- Switch to your desired policy
- Remove permissions to the "original" archive
This way, you can keep the archives for all data > 1 Year, and hide it from the user.
All other data is in the journal anyway.
Cheers
