ManualArchiveMessageClassCheck

Everyone is probably familiar with setting message classes on their mailbox archiving policies in Enterprise Vault.  When message classes are unticked in the policy, scheduled archiving won’t archive those types.

An end-user who has the store in vault button, however, can still manually archive these “disallowed” types.  In order to prevent this the following registry key should be added :

ManualArchiveMessageClassCheck

Location
HKEY_LOCAL_MACHINE
SOFTWARE
KVS
Enterprise Vault
Agents
Content
DWORD.
0 – [Default] Archive all items when a user performs a manual archiving operation.
1 – Archive only those items that belong to the message classes that are listed in the mailbox policy

Description
Specifies whether, when a user performs a manual archiving operation, Enterprise Vault archives only those items that belong to the message classes that are in the mailbox policy. By default, Enterprise Vault archives all items when manual archiving is performed. Enterprise Vault ignores the message class list that is in the mailbox policy.
This registry value does not affect automatic, background archiving runs.

Then if your message classes in your policy don’t allow archiving of delivery reports :

When you try on the client, the item will go pending, and then revert back to a normal item.

The DTRACE will show things like this :
