Has made it significantly easier to handle rare litigation requests
The speed of it is valuable. I am able to search even 10,000 mailboxes for specific content. It helps search and accommodate the often limited information provided by users regarding what they need. It provides a solid starting point, and then we are able to refine the data from there. That has been very helpful because we do not always get enough information from our users to know what to look for. For example, a user is missing an email from x date but does not know anything else. In such a case, I give them a list of emails to look at so that they can tell me what they are missing. It is not a lack of the tool. It is more of a lack of the user providing info.
