Move databases without having to update user's workspace manually

Hi,

I would like to move old mail files that are still be accessed by some people in the organisation even though the owners have left into a exstaff directory so I can monitor diskspace.

However, most of the people using these files are partners and it would be considered an interuption to send them a new link etc.

Does anyone know how I can move the files and automaticaly update the links?

Thanks!
