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

"Knovos eZSuite has a nice interface and performance well. It has a good processing speed."
"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."
"I think eDiscovery Premium has made dealing with data from Teams much more accessible than any other platform."
"Microsoft Purview eDiscovery has saved me personally a lot of time because I can query it, and it touches everything we have as a full Microsoft shop."
"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."
"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."
"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."
 

Cons

"The solution could improve by having better integration with different platforms. Additionally, the audio and video could have better support."
"I would suggest adding more platforms."
"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."
"The sorting and filtering of the result data need improvement, and the interface for writing queries is not user-friendly for business users. We still need all the backend stuff. We have to use Graph API to interface with everything and create custom interfaces on the front end to make it easier for the end users, which is costly. The reporting, sorting, and filtering capabilities that other products have aren't available natively in Purview."
"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."
"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."
"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."
 

Pricing and Cost Advice

"We were using a trial license of the solution."
"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."
"Microsoft Purview eDiscovery comes as part of Microsoft 365 licenses."
"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."
