Senior System Engineer at a sports company with 5,001-10,000 employees

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.

Director Consulting SAP OpenText en Entelgy at DCL Consultores EIM SL

A stable and scalable hybrid solution with easy setup

The solution is scalable. It has three levels. You have the presentation area that can be escalated to the balance sheet. You have the back-end area that can be escalated using higher viability to configure more application servers. Also, the area of storage can be increased. We usually cater to enterprise solutions but have small- and medium-sized customers. It starts with 25 users and goes up to 100s and 1000s.

Quotes from Members

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

Pros

"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 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 return on investment is saving the equivalent of one or two full-time IT department employees and a few hours per week for legal staff."

"The most valuable features are automatic content logging tagging. Performing these tasks manually would be impossible. Since most of our data is already in Microsoft, it's convenient to run it through this tool."

"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."

"Our legal team benefits from using Microsoft Purview eDiscovery."

"Tasks that took an entire day before we implemented Purview now take just 30 minutes."

More Microsoft Purview eDiscovery pros

"The technical support is excellent."

"The solution is very stable."

"I like the processing feature on the product because it does everything at once, i.e, indexing, recovery, keyword searches, etc."

"Data Recovery: Its ability to repair damaged partitions and uncover hidden partitions from within the tool, and allow further analysis."

"The most important feature we've found is the Enscripts. That is one powerful feature that I, personally, love to use."

"It speeds up the process, so I can meet my deadlines."

"It indexes much faster, and is more reflexive because of the Enscripts."

Cons

"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 sorting and filtering of the result data need improvement, and the interface for writing queries is not user-friendly for business users."

"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."

"Microsoft Purview eDiscovery should be cheaper."

"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."

"I would suggest adding more platforms. Currently, it's compatible with OneDrive, Teams, SharePoint, and Exchange. Adding more features, as Microsoft continues to expand their cloud offerings, would be beneficial. Exploring options like Azure Files might be an avenue for improvement."

"We find that many critical functions are available only to E5 license holders."

"I would suggest adding more platforms."

More Microsoft Purview eDiscovery cons

"Ease of use and learning curve need improvement."

"I would like to see a capability to ingest and absorb more data. That would be really good. It currently is lacking this function."

"In the past, incident response time for tech support was slow."

"There were minor UI bugs."

"Sometimes the application can take more time to complete the image processing or fail at the end of the process."

"We have come across problems with the end-case. We could not find an email discovery type of module and there was not flexibility with the email."

"The reporting is a bit unreliable. It needs to be better."

Pricing and Cost Advice

"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."

"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."

"The costs associated with E5 licensing are currently expensive for us, so we use the E3 license, which comes with fewer features and functionalities."

"Microsoft Purview eDiscovery comes as part of Microsoft 365 licenses."

"The product is affordable and user-friendly."

"We have a license. And, we found the cost high. We contacted them and talked to them about the ratio of the US dollar versus the Indian rupee and then we came to a solution."

"EnCase is an affordable solution."
