Use The Enterprise Vault Client

To delete hidden messages from a mailbox you will first need to add the following registry key

Scroll down to the hidden message and select it, once selected select the Delete Hidden Message button. 

That’s it. To get a new hidden message written to the mailbox you need to synchronize that user manually or wait for the next synchronization run.

There should be the following hidden messages.


Use EVPM to ZAP a mailbox

Create a new EVPM Initialization file

Save the file in notepad in UNICODE format, with an .ini extension., E.G. EVPM.ini


DirectoryComputerName = DIR_SERVER
Sitename = SITE 

DistinguishedName = /o=org/ou=mailboxou/cn=recipients/cn=mailboxcname 

Name = Mailboxroot
Zap = True


Run EVPM.exe from \Program Files\Enterprise Vault as the Enterprise Vault Service Account. 

The syntax for EVPM:

EVPM [-?] [-e Exchange Server] [-m Privileged Mailbox] [-f Initialization File]

E.G. "C:\Program Files\Enterprise Vault\EVPM.exe" -e EXSEVER -m EV_PRIV_MBX -f C:\Program Files\Enterprise Vault\Scripts\EVPM\zap.ini

NOTE: If ZAPPING a journaling mailbox, it is important to stop the Journaling Service first, zap the mailbox, and then restart the journaling service.
