We have a user who has left who has a lot of emails in their account and in their archive that we wish to retain and have potential access to. We'd also like to be able to remove this user from the system and have their archive accessible by another user or users. Is there a easy way to do this ?

If we cannot re-assign the archive to an existing user, can it be converted to a format that is accessible by some other system, or any easy bulk email operations to foirward this to a different account that we could maintain and folderize to retain multiple old account email histories.

Any reasonable suggestions considered !
