Larger File Size Upload Limits

1 May 2021

This has been around a while now, but has had little fanfare, so trumpets at the ready…

With the advent of “working from home” the new COVID-19 norm, remote work and learning has increased significantly. This means there is now a greater need to reliably and securely share large files, such as 4K or 8K video files, 3D models, CAD files, photographs or even Excel files (!) with co-workers, clients and peers.

Since the end of March allegedly (!), Microsoft has made it easier to store, synchronise and share large files in Microsoft 365. The company has increased the upload file size limit for Microsoft 365 from 100 GB to 250 GB, which includes uploads of files into SharePoint, Teams, and OneDrive.

Microsoft has achieved the 250 GB limit by optimising storage for upload performance—each file is split into chunks and each piece is encrypted with a unique key. All your files are backed up in Azure Storage, ensuring high availability and performance. You can easily upload and download your large files when you need them, where you need them.

With something called differential sync, only the changes that you and your collaborators make are synchronised, shortening the amount of time it takes you to synchronise, helping improve performance and reducing network utilisation.
