I am curious if the eDiscovery feature will search and find emails that use Entrust for encryption. Does anyone know if this is possible?

Hi MichaelColley,

Only option I'm aware is it supports IRM Encryption or MS tech encryption only. All other encryption methods goes to the unsearchable catagory. I believe Entrust is a S\MIME based encryption which is not supported for eDiscovery.

Unsearchable items in Exchange eDiscovery

• A file is encrypted with non-Microsoft technologies.
• Attached files encrypted with Microsoft technologies are indexed by Exchange Search and will be searched. Files encrypted with non-Microsoft technologies are returned as unsearchable.

• Email messages encrypted with S/MIME aren't indexed and are considered unsearchable items. This includes encrypted messages with or without file attachments.

For a successful eDiscovery search, your organization may be required to review unsearchable items. You can specify whether to include unsearchable items when you copy eDiscovery search results to a discovery mailbox or export results to a PST file.

Include unsearchable: items She can choose whether she wants to include "unsearchable" items, items that our indexing system may not be able to handle, such as a corrupted item, a password-protected zip attachment, or an item encrypted with something other than Information Rights Management. This check box gives her the option to include those two in case she wants to review them manually just to make sure she's doing her due diligence and not missing anything.

Entrust Secure Email Certificates (Enterprise)

Entrust Secure Email Certificates are publicly trusted S/MIME certificates that enable individuals or organizations to encrypt and digitally sign emails and other documents.

Below is what Enstrust Whitepaper has to say: You might have to deploy a seperate solution to eDiscover these messages.

The objective of this whitepaper is to describe solutions for both forensic and real-time content

control. Effective content control is an end-to-end problem that requires solutions that can be

integrated seamlessly in the enterpriseif content is sensitive and policy allows that it be sent,

ensure that it is encrypted; if it is required for e-discovery, put it in the archive and make sure it is

pre-tagged for easier classification. Look for vendors that offer as much of the solution as

possible and who have partnerships
