Access Vaulted items in different EV Site - with VV support

I have this issue but with a twist:

https://www-secure.symantec.com/connect/forums/access-vaulted-items-different-ev-site

users do not use stubs at all, everything that is archived goes straight to virtual vault.

according to the help files in EV documents:

• When you want users to be able to access archived items from mailbox shortcuts in other vault sites

ok, so if i don't have stubs, how can I give permissions so that I can synch VV from other site to outlook and not use archive explorer?

ev version 9.0.2
