eDiscovery Manager at a financial services firm with 10,001+ employees
Stable with administrative aspects and an easy to navigate backend
The initial setup isn't exactly straightforward. It's a little complex. A company really should hire some experts that can navigate the implementation. Including testing, the deployment took about three hours. It's not a long or drawn-out process. Technically, you only need one person to handle the setup, however, it's advisable to at least have two people who are knowledgeable. In our case, we implemented it first in a separate environment and, once we saw everything was working as it should, then we sent it to production. There isn't much maintenance required. There's another application that handles that, however, we do have to monitor logs and the server where we put the searches.

Tasks that took an entire day before we implemented the solution now take just 30 minutes.
The most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive. It enables a streamlined, unified process for searching across these platforms. It is critical for Purview to be able to connect to iOS, Mac, and Android devices and data in other SaaS apps. From a support perspective, I can do things while I'm eating lunch or something else. It's more dynamic and responsive. I think everybody appreciates it. We're not tied to one device. Purview's multi-cloud capabilities are also essential for the same reasons. Keeping everything under one umbrella further increases the time savings. Purview accounts for critical regulations from around the world. This is crucial because we hold ourselves accountable to standards and need to align with them. Working at a law firm, we have clients who dictate to us what standards they expect. The visibility is excellent. As we move more things into the cloud, more opportunities exist to put everything under one umbrella.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Overall, it's a very powerful tool."
"Creating and running queries on the solution is very good."
"Our legal team benefits from using Microsoft Purview eDiscovery."
"The ability to query everything that's in Microsoft and send links or add people, like managers, to review the documents is valuable. It's easy as I don't have to download and email anything. I just add them as a reviewer, and they can access it from there."
"The most valuable feature of Microsoft Purview eDiscovery is the content search. We can use it to find the data we need by searching for keywords, phrases, or the sender or recipient. It helps us gather information from current employees or ones who have left the company."
"The most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive. It enables a streamlined, unified process for searching across these platforms."
"I think eDiscovery Premium has made dealing with data from Teams much more accessible than any other platform."
"The machine learning wasn't half bad. I really like that part. I thought it was novel. It pretty much automated it, once you trained the model."
"The tool has been beneficial. Some of our previous users left the organization without sharing the information they had at a personal level. This information was related to the organization, and they didn't disclose it. Thanks to the product, it's easy for me to search and find out what communication a specific user has done, whether it's from SharePoint or any other platform. With Microsoft Purview eDiscovery, we can easily retrieve and restore this data."
"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."
 

Cons

"The solution needs to be more user-friendly when it comes to errors on the search."
"The initial setup is a bit complex."
"Microsoft Purview eDiscovery should be cheaper."
"The query language can be time-consuming to figure out if you don't know it initially."
"I would suggest adding more platforms."
"Purview Data Loss Protection for remediating policy violations needs refinement, for example, in defining what constitutes a credit card because that is where I get the most false positives."
"Purview eDiscovery works, but it's not entirely perfect. There were times when search results would get hung up or error codes would be presented and we'd have to contact Microsoft to get that sorted out."
"We find that many critical functions are available only to E5 license holders. It would be beneficial to have more options available for E3 customers. Enhanced Teams functionalities and better capture of text message data, both SMS and MMS, would also be improvements."
"I see two significant challenges with many of my clients. One is that there are some functionality gaps compared to specialized tools in the legal industry, like a legal hold tool or a document review tool. They have features that Purview eDiscovery lacks. Those gaps create a situation where I almost have to do things twice. I need to collect all my data in eDiscovery and ship it to another platform to complete the review."
"The sorting and filtering of the result data need improvement, and the interface for writing queries is not user-friendly for business users."
 

Pricing and Cost Advice

Information not available
"The costs associated with E5 licensing are currently expensive for us, so we use the E3 license, which comes with fewer features and functionalities."
"With the full bundle, pricing is not a significant concern. As an M3, I find the Purview pricing of 1250 per user worthwhile."
"In the positions that I've had through contracting over the years, I've heard talk of it being overpriced and underperforming compared to its competitors."
"Microsoft Purview eDiscovery comes as part of Microsoft 365 licenses."
"The pricing and licensing with Microsoft can be complex, and licensing is known to be a challenge because it changes frequently. While the licensing for Purview is not as tricky as other Microsoft products, navigating licenses since the shift to E3 and E5 plans has been a task, as individual licenses must now be purchased separately."
