Happy new year and welcome to 2021. We are thrilled to begin this year with some exciting news.

Microsoft 365 users will be getting expanded file-size support, allowing files to be shared that are 250GB maximum in size, per a Microsoft announcement earlier this week.

As remote work and learning increases so does the need to reliably and securely share large files-4K or 8K video files, 3D models, CAD files, or large scientific data sets-with co-workers, clients and peers.  At Microsoft they're perpetually working to enable and support workers all over the world -  striving to innovate and empower users to be more productive. 

We are pleased to announce that Microsoft is making it easier than ever for you to store, sync, and share large files in Microsoft 365.

Latest improvement will help increase the upload file size limit for Microsoft 365 from 100 GB to 250 GB — which includes uploads of files into SharePoint, Teams, and OneDrive. So now, you will be able to easily share large files like a 3D model of a new building, a client commercial shot in 8K video or large videos for educational projects. And this change doesn’t just apply to businesses and schools. If you use OneDrive, for personal use, you can easily upload or your family video album to share with your relatives or upload that zip file containing a large PC game with your friends.

Microsoft achieved the 250 GB limit by optimizing 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.

And you need not worry about syncing these large files - with differential sync, only the changes that you and your collaborators make are synced—shortening the amount of time it takes you to sync, helping improve performance and reducing network utilization. Finally, as always, your files are always with you on any device, wherever you go, whether you’re editing files in OneDrive, sharing projects for review in SharePoint, or collaborating in Teams.

Support for 250 GB file size upload will be rolling out by the end of January and we are looking forward to general availability by end of this quarter.
