OneDrive stuck on "getting in sync" icons

Not sure if this is still an issue for some users but I recently had this happen for one of my clients. I realized after some testing that if I renamed one of the folders showing the "Getting in Sync" status, created a new folder, then copied over all the items from that folder, the issue would subside. When I proceeded to delete the original folder, it prompted me if I wanted to remove a temp system file.

This helped me realize that the folders in question that would not sync all had locked/corrupt temp system files (which are hidden by default) and are not meant to sync with the OneDrive Client. This included temp files for word docs, thumbnail/icon database files, etc.

Moving forward I temporarily changed the folder options as follows (Windows 10):

1. In File Explorer > View Tab > Options (All the way to the right)

2. View Tab

3. Select the radio button for "Show hidden files, folders, and drives"

4. Finally uncheck the box that shows "Hide protected operating system files (Recommended)"

Once that was done, I could browse through each folder and remove all locked/corrupted temp files and the folder would show as synced after that.

Note: Remember to undo the folder options mentioned above when done. 

This may not be the end all solution for everyone but it helped in my situation.
