Offline access to old emails urgently needed

Hello everybody,

in our company we are using Enterprise Vault for email archiving according to auditing requirements (no local .pst files allowed anymore).

That works fine so far, except for our sales people who are travelling often and need to access very old archived emails on request at the customer's site (where is no Internet access provided).

That is a big issue, as far as I could find out so far, there is no solution to open e. g. EV archived emails from 3 years ago.

Is there any solution you can suggest?

Thanks a lot,

Nicole
