It is possible to search the message bodies of certain signed messages, however; these messages will not be searched by default. It is not possible to search encrypted mesasges, non-text attachments, or the message body if the signature is invalid (e.g., revoked, outdated, etc).
When messages are signed, the message contents are actually mailed as an attachment named "smime.p7m" and attached to the message. When the signature is valid, Outlook automatically displays the message contents as though it were the message body. In some instances you will even see the paperclip icon indicating that there is an attachment, though no attachments are displayed. If you can view the message within Outlook and there are no errors with the signature, Identity Finder should be able to search the message body.
In order to enable signed messages to be included in the search, the following configuration is required.
- Ensure that E-Mail searching is enabled and that searching of E-Mail Attachments is also enabled. These search locations are enabled when their ribbon buttons are highlighted orange, as shown in the Identity Finder Help topics, Searching E-Mails for Personal Information and Searching E-Mail Attachments.
- Ensure that Outlook and/or Exchange searching is configured properly to search the locations containing the target messages. Please refer to the Identity Finder Help topic, Searching Outlook and Exchange for Personal Information.
- Change the file type search from the default of "Only common file types" to "Custom file type list" and add p7m as a valid file extension. More information can be found in the Identity Finder Help topic, Managing the Custom File Type List.
- Verify that Identity Finder is attempting to search the messages by following the steps detailed in the article, Ensuring that Identity Finder is attempting to search the specified locations.
