Update: We’re rolling out the ability to see who viewed your files on the File Card on OneDrive for Business. You can hover over a file on the web to get to this. Let us know what you think!
While we don’t have an update here for adding metadata tags to files, we are continuing to explore this as part of the future roadmap. We recently announced the ability to edit existing metadata from within Teams and will continue to invest in metadata scenarios.
Wanted to provide an update here: this is something we’re planning on doing, but don’t have a timeframe to share yet
