I have a question regarding Enterprise Vault.
Here’s a little background :
We have Enterprise Vault 184.108.40.2067 (64bits) that was used to archive Exchange 2007.
We did a project to migrate all our mailboxes to Office365.
A new Exchange 2013 was built to setup an Hybrid solution with Office365.
We asked our users to bring back their important emails from the Vault to their mailbox
Mailboxes were migrated from Ex2007 to 2013 and then to Office365.
After all mailboxes were migrated, Ex2007 was decommissioned but Ent Vault was kept in case we needed to search for missing emails. The search function works fine (we essentially use for journal mailbox). EV was supposed to be decommissioned in January 2017 but we were asked to wait… Exchange 2013 is still operational.
We are at a point that journaling mailbox search is not sufficient : we would need to export the search result to PST. This, doesn’t seem to be doable without the original Ex2007 journal mailbox. What would be the better option for us?
