I have a client working with litigation to obtain some specific emails which pertain to a current lawsuit. I have been asked to perform an eDiscovery search on some keywords which I am able to access via protection.office.com
. The results did find a ton of information. Something strange happened after I ran the search and it completed. I did an exact search of item AND item AND item specifically to get emails directly related to those key words within email messages itself. The litigators need this information by Thursday. The process did complete after I told the results to export and I did successfully download all the data along with the SharePoint data and between 2 searches was able to obtain 6 PST file exports. I have added all 6 of those PST files to Outlook however our client is complaining he is having trouble finding any related emails (With those keysearch names) searching. He is using Outlook 365. We have done this twice and get the same result. Our client thinks we are incompetent and unable to give him what he wants. I have spoken with Microsoft who has validated I have done the searches in eDiscovery properly and has to escalate to a higher team why:
1. Search results are pulling emails with no relevancy as to keywords in the email and spitting out data totally irrelevant to the item AND item AND item search.
2. Why Outlook (When searching for one of those keywords) comes up with no results even though the search results show in the compliance portal.
Indexing is turned on as well as cache mode on his workstation. Has anyone here worked with eDiscovery and can tell me why after downloading and importing those PST search files nothing works in regards to relevance of key words specific in email messages during a search? This is pretty high priority. The last export and download I did between 2 searches was almost 100gig of data. Am I missing something doing these eDiscovery searches? Any help as always is appreciated.
