How Retention is Changing for SharePoint Online’s Preservation Hold Library

 

The preservation hold library is an important component of SharePoint Online retention processing.

Basically, instead of storing multiple versions of a file, SharePoint Online will hold a single file containing all the updates. It seems like a good change to make. We’ll know more when it rolls out.
