Access to an Email Prior to Employment Via End-user Search in CommVault Email Archive

A coworker and I have been doing a lot of work on the CommVault email archiving and compliance products here lately. CommVault email compliance solutions provide two ways to access data collected via email compliance archiving agents. The end-user compliance portal allows a user to log in and search only their email whereas the compliance portal allows search of all email that has been collected via journaling. The issue we were able to reproduce was the following:

A user with a specific employment date (lets say 10.1.2010 for instance) could log in and see email that was sent prior to his/her employment date. They couldn’t see ALL email, just certain email. [more]

Long story short, as part of a troubleshooting task with CommVault support, our customer had created  a “special” configuration that enabled the compliance agents to basically harvest all mail in the Exchange environment from all mailboxes. Part of the work that the CommVault indexing engine does is to look at the email message and “mark” the message in such a way that it can be found by associated parties via the end-user search portal. It does this by looking up all parties on the email in active directory, then it associates the message with all the user GUIDs that should have access to the message via end-user search. In our case specifically, when all the emails were “harvested” from all exchange mailboxes, a specific set of emails that were sent to a distribution group were pulled in. The indexing engine expands those distribution groups and links the GUIDs accordingly. Emails to that distribution group go back farther back in time than the employment of the user in question, but the user is CURRENTLY a member of the distribution group. So, when the indexing server expanded the group, that user was associated….and viola, access to an email prior to employment via end-user search.
