OneDrive stuck on Processing changes

You have a OneDrive file open.

Close the file once you finish editing.

You're syncing a lot of files.

No action required. OneDrive will upload all files, but this may take some time if your internet speed is slow.

Run an internet speed test to make sure the problem is not elsewhere.

You're trying to sync a very large file, such as a compressed ZIP archive, a long video or your Outlook PST or OST offline data files.

You can move large files such as email data files out of your OneDrive storage folders, or choose not to sync folders which have large files such as videos in them.

Any OneDrive log files titled "aria-debug" can be safely deleted.

For more information, read How to remove an Outlook data file from OneDrive.

You are not signed in.

If you changed your password, OneDrive might need you to sign in again.

You have just signed in, or have just updated your computer.

No action required. OneDrive will eventually re-sync all files, but this may take some time if there were a lot of changes or your internet speed is slow.

Run an internet speed test to make sure the problem is not elsewhere.

Unknown/hidden files causing the error.

Select the OneDrive cloud icon in the taskbar/menu bar to show the list of all files open, being synced or have recently synced.

Temporary or hidden files may also be blocking sync.

Read OneDrive status stuck on "Sync pending" for more information.

If "Processing changes" remains, read Unlink and re-link OneDrive to help reset your OneDrive.
