One Drive not uploading file

This problem can happen due to several reasons. Here are some steps maybe you can follow to troubleshoot the issue:

Ensure your OneDrive app is fully up-to-date.

Clear OneDrive Cache, Sometimes, cached data can cause upload issues.

Try Uploading via Web Browser, the desktop OneDrive client can have issues, so try uploading the file directly via the OneDrive website

Check for File Path Length, If the file path (folder structure + file name) exceeds the OneDrive limit (around 400 characters), it might cause errors during upload.

Upload in Smaller Parts, uploading a large file can be problematic, you can consider compressing the file into smaller parts.

Some antivirus programs or firewalls might interfere with file uploads. Try temporarily disabling them and see if the issue persists.

OneDrive Repair, this may help resolve any internal errors causing the upload issue.
