How to increase OneDrive for Business storage up to 5TB

You must have known that OneDrive for Business storage has a limitation of 1TB but what if you have utilized the full capacity (1TB). There is no such announcement for the same, but the limit is not 1TB. In this article, we will see how we can increase the storage capacity for OneDrive for Business up to 5TB through PowerShell.

As per one of the Microsoft articles “If your organization has a qualifying Office 365 plan and 5 or more users, you can change the storage space to more than 5TB”. So as per this statement, we can get more than 5TB as well. That means the limitation is not 5TB as well.

Increasing the storage from 1TB to 5TB can be done with the help of your Microsoft 365 Administrator through PowerShell, but going beyond 5TB, you will need the help of Microsoft Support with justification and then it might get increased up to 25TB quota.
