    Yes. Documentation is here.

     

    Although SharePoint Online can store 30 million documents per library, the sync performance of OneDrive may start to decline when you store more than 100,000 files in a single OneDrive for Business site or team site library. To resolve this limitation, ensure that files are stored in multiple folders/libraries. If you have more than 100,000 files in a OneDrive for Business site, you may need to wait an extended period of time with OneDrive continuously syncing before sync can complete.
     
    There are other limits on viewing a document library using the web that may affect how you structure your files in OneDrive.
     
    We're always working to optimize OneDrive to better handle libraries with a large number of files.

Hi Ivan,

The wide use of NGSC with such as data volume does not bode well. Are you able to determine how many users have synched this document library (and how much data is offline)? This will also place a burden on the SharePoint infrastructure. Understanding the "size" of the problem is key to determine the best way to resolve it. I am not a fan of offline tools (also from data security + RM perspective).

The good news is: I can help you with the 2 original problems.
Browsing
My company has developed a browser-based tool named Migration Manager that shows SharePoint content as a windows explorer tree in browser. It uses REST API to retrieve the data from SharePoint. Combined with caching techniques this results in a very fast solution. Check out http://www.slimapplications.com/product/migration-manager/ for details.

Viewing emails
The OOTB msg viewing capabilities of SharePoint do not expose the email attachments. Migration manager does provide this functionality in the browser: users can click on email attachments and directly open them (without any plugins). There is a 15-day full functionality trial available. I can also grant you access to our SharePoint Online demo environment if you want to see it in action.
