Recent Unlimited Storage Change
Microsoft in August made modifications to its OneDrive for Business storage plans, removing its unlimited offering for business users. OneDrive for Business (Plan 2) used to be a popular choice for large organizations that needed a lot of storage space, especially for media files like videos and art. This plan gave unlimited storage every month for about $10 per user, without taxes. But Microsoft has stopped giving unlimited storage to new customers.
Now, OneDrive for Business (Plan 1) is the main option, with 1TB of storage by default. This can go up to 5TB depending on how many users there are. Before, OneDrive for Business (Plan 2) had unlimited storage with some conditions. Organizations had to have at least five users signed up, with a starting limit of 1TB per user. More storage, up to 25TB, could be asked from Microsoft support.
