The list was curated based on the items that the public has requested on Microsoft's feedback portal for Microsoft 365 services. As usual, we will only be listing issues that are "open", sorted by upvote count. As such, capabilities which Microsoft has rolled out in general availability or preview will be excluded. Also note that this list may cover multiple platforms and does not only include Windows. With that said, let's begin!

1. Reassess the possibility to ignore or exclude selected OneDrive folders and files from the sync process - 8,468 upvotes
   Microsoft: This feature has rolled out for files and we are looking to expanding it to folders in the future.
2. Enable syncing over LAN - 7,857 upvotes

3. Allow shared folders to be stored within sub folders - 5,329 upvotes

   2) For OneDrive across business and personal, enable shared folders to be placed into subfolders.
