Purview EXPORTS unreliable and missing "Top-of-information-store" folder
Has anyone noticed an issue where the exported PST files are either empty or missing folders? I don't normally check every PST file that I export, but after hearing from customers that there are either no emails or missing folders, I started to check after each export.
I am noticing that the Seach and Export process seems to be fine and the Downloaded PST file show the correct size, but when i open the PST files, I'm seeing that they contain no emails OR they are missing folders - including the "Top-of-information-store" folder. When i look at the Properties > Folder Size settings, i can see that the PST file thinks that all the folders are there.
This is incredibly tough to work with since I am now checking each PST file and then having to rerun the search/export/download all over again. It's been like this for about 3 weeks.

Hi Prathista Ilango. I'm exporting emails from 8 custodians, many of which are in the common email threads. So it seems odd that this only happens to half of them. Also, the emails ARE there, but the issue is that the TOIS shows up as a "calendar" folder, so it doesn't show up when you are in the "email" folder.
NOTE - this only started 3 weeks ago. It feels like another situation where a change was made and we're left to try and figure it out. Luckily, enough people are talking about this issue and pointed me to look at the calendar.

Hello ChungNg ,
Sorry that you are running into this. A couple of quick things worth double‑checking here:
- Have you reviewed the Export considerations to confirm the export doesn’t fall under any scenarios where content may be excluded (for example, DLP‑restricted items, locked SharePoint sites, or access limitations)?
Reference: https://learn.microsoft.com/en-us/purview/edisc-search-export#export-considerations - It’s also a good idea to review the best practices for downloading export packages, as download or extraction issues can sometimes lead to incomplete or unexpected results when opening PST files.

Hope this helps!
