Understanding OneDrive Storage Plans, Capacity and Key Limitations

How information is stored and accessed plays an integral role in how we collaborate and work. In this blog, we’ll cover the growing appeal of OneDrive storage and its available storage plans, OneDrive storage capacity and file size limits, how you can go about adding storage capacity when needed, and key service limitations to be aware of.

The evolution of OneDrive storage

Microsoft OneDrive has evolved considerably since it was first released in 2007 as Windows Live SkyDrive. Initially, SkyDrive storage capacities were limited to 5GB and soon increased to 25GB. File size limits were initially set to 50MB and increased to 100MB in 2011. SkyDrive was renamed OneDrive in 2014. Recent changes to OneDrive have significantly increased both the maximum storage capacity and the file size limits.

How much space do you get on OneDrive?

Microsoft has provided several OneDrive plans to choose from for both home and business use. The plans offer considerable flexibility and storage size options.

Home storage plans

The Microsoft 365 Personal and Family plans includes Microsoft Office applications for each person as well. Microsoft 365 subscribers can also purchase additional storage. For example, another 1TB of storage can be added for $9.99 per month. In addition, Microsoft 365 subscribers have an unlimited personal vault, 30-day file restoration, increased sharing limits, password-protected sharing links, and expiring sharing links.

What can you store on OneDrive?

As a user, you can store photos, documents, videos and practically all file types in OneDrive.

All Microsoft 365 Personal and Family plans and Business storage plans support file sizes up to 100GB. In January 2021, Microsoft announced that the supported file size was increased to 250GB. General availability for 250GB file size is expected by the end of the first quarter of 2021.

OneDrive supports up to 50,000 major versions and 511 minor versions.

OneDrive allows storage of almost all file names and file types. The exceptions are listed below in the limitations.


  • Characters that aren't allowed in file and folder names in OneDrive for home, OneDrive for work or school and SharePoint in Microsoft 365 are: " * : < > ? / \ |
  • Leading and trailing spaces in file or folder names also aren't allowed.
  • These names aren't allowed for files or folders: .lock, CON, PRN, AUX, NUL, COM0 - COM9, LPT0 - LPT9, _vti_, desktop.ini, any filename starting with ~$.
  • Temporary TMP files will not be synced to OneDrive.
  • Outlook .PST files are supported; however, they are synced less frequently compared to other file types to reduce network traffic.

To learn more about file and sync limits, see SharePoint limits and Invalid file names and file types.
