If you use Microsoft Edge or a recent version of other popular web browsers, you can upload files to OneDrive up to 250GB in size. If you use an older web browser, the maximum file size is 300 MB.
Notebooks saved to OneDrive are limited to 2 GB.
Tips:
You can upload files up to 250GB in size if you use the OneDrive app.
To transfer large files or many files, it is recommended to add the files to the OneDrive desktop application instead of using the Upload button on the website.
