Overpriced for storing documents, it is not user-friendly, and the support is paid hourly
I hate everything about it this product. It is not user-friendly. There is maybe one person in our office who has any proficiency with it. I don't like it at all. For litigation, what I wanted was a one-stop shop. Once the document is produced as an exhibit for example, then I want to be able to annotate on that document and use that during my trial versus using Casepoint for the production. However, I now have to somehow download that production into several PDFs. I can't use the sort feature or other features. I would prefer to leave it on Casepoint because now I have tagged it for witnesses, which is helpful in litigation, but the notes features on Casepoint is a tiny box in the bottom right of the document and that is not really helpful to me because of the way that I use documents in the trial is, for example, if you are going to be my witness, I draft a direct examination of you. When I get to the point in my direct examination where I want to cover an exhibit that I'm trying to admit with you, I hyperlink that. The document that I have hyperlinked has my questions and notes on the document, that I'm going to ask you about, but I can't do that in Casepoint.

Enables us to guarantee that we followed the regulations
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. Purview's inclusion of critical regulations is essential. Lawyers will ask how we gathered information. With Purview, we can guarantee that we've followed the regulations. The visibility into what's happening and who has access is great for legal matters and saves us a lot of time.

Quotes from Members

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

Pros

"The initial setup was quite straightforward. It's really just a matter of plug-and-play."
"Casepoint is scalable. I don't have any issues with the scalability of this solution."
"Tasks that took an entire day before we implemented Purview now take just 30 minutes."
"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 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."
"Our legal team benefits from using Microsoft Purview eDiscovery."
"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."
"Purview eDiscovery has made it significantly easier to handle rare litigation requests."
"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."
 

Cons

"I hate everything about it this product. It is not user-friendly."
"The biggest pain point for me and most people is that when we have to update our passwords, we have to go back in and remap our web folders."
"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."
"The query language can be time-consuming to figure out if you don't know it initially."
"It has been one of the most solid tools I have worked with. However, 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."
"Microsoft Purview eDiscovery should be cheaper."
"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."
"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."
"The query language can be time-consuming to figure out if you don't know it initially. While there are options with dropdowns to select criteria, having a natural language feature would be beneficial. Copilot is expected to add such functionality in the future."
"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

"It's ridiculously overpriced and the bills are ridiculous."
"Microsoft Purview eDiscovery comes as part of Microsoft 365 licenses."
"The costs associated with E5 licensing are currently expensive for us, so we use the E3 license, which comes with fewer features and functionalities."
"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."
"With the full bundle, pricing is not a significant concern. As an M3, I find the Purview pricing of 1250 per user worthwhile."
"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."
