What we are trying to accomplish is that for users that do leave the Company and their Mailbox will be removed within Exchange, we currently do have a 0-day archiving Mailbox policy set, which fully archives and removes mail from the Mailbox. However, it does seem that EV currently does not take care of the "Recoverable Items Folders" on an indivdual mailbox basis.
In researching, I have found a registry setting that would be available (RecoverTombstoneItems) to set. However, this is a Server Setting and does not seem to be possible to affect individual mailboxes (like an all or nothing setting). If we would have this in place, the Problem here is that Virual Vault would also have this Information from the recoverable items which then would be synced to each active client (5000+ in our case).
Would there be a way to avoid this being an all or nothing setting rather than to be available on a per-mailbox-basis (probably within mailbox policy settings that will then affect a provisioning group) to accomplish our goal?
As the functionality is already there to a certain point, I could imagine that this would not be that much of an effort to raise the functionality to be broken down per mailbox/mailbox policy.
