If you are using OneDrive for Business and Syncing local folders you may have run into the problem of some files not syncing with the cloud. You’ll see the icon in the system tray for OneDrive for Business showing an alert. It can be frustrating to figure out why the files are not syncing. There are a few things to look for when this happens:
- There may be special characters used in the file name – which work fine on the local computer, but don’t work for saving in OneDrive.
- I find it’s best to use the standard text/numeric characters and some basic “-” “_” characters when naming files.
- The file you are trying to sync may be too large or you may have too many files in the OneDrive for Business folder to sync.
- You can sync up to 20,000 items in your OneDrive for Business library, including folders and files.
- In any library, you can download files up to 2 GB.
- Your credentials may have been changed on Office365/OneDrive, but your computer saved the old password.
- Go to the Control Panel or Search from the Start Screen for “Credentials Manager”
- Open Credentials Manager. Delete the Office14/Office15/Office365 Credentials.
- Open OneDrive for Business and Sync and enter your current username and password in when it prompts you.
