Upcoming changes to Microsoft Purview eDiscovery
Has anyone been able to export PST files larger than 10GB without using third-party tools?

Recently tried content search. The Data is more than 59GB and it only downloads the 10GB PSTs. There are several PSTs, but it only downloads 2 PSTs. Tried to download again and it downloads the random files from the list of PSTs and Items files. I have opened a ticket with Microsoft for that. Looks like it's a bug in new eDiscovery

You can bypass that with rclone, it has a CLI console that can be used on powershell scripts as a workaround and works great. Have been using it for ages and never failed to me.
Btw are you able to let me know the commands that you have used, to achieve the search and export with this new change? And license needed to perform that too?- ChungNgJul 18, 2025Copper Contributor
I actually haven't done anything other than use the native Purview GUI so far. I'll have to check out rclone. Thanks.

Ah ok, so I think I may have misunderstood your question. Have mentioned rclone for a situation where you have the PST 10GB files already downloaded, and you wanted to upload to a onedrive or something. Unfortunately the 10GB max per PST file shown on exports is a default behaviour that was happening even before this "downgrade".
