Are OneDrive files included in SharePoint Online storage limit?

[Jay Carper]

I am having a hard time finding a straight answer to this question, but it seems like something that needs to be spelled out as plainly as possible.

Do files in OneDrive for Business count toward the tenant's total Sharepoint Online storage limit? A yes or no answer would be fantastic.

For example... SharePoint Online allows 1 TB plus 10 GB for each licensed user. OneDrive allows 1 TB (default) for each licensed user. If the tenant's SharePoint Online total storage limit is 2 TB, this tenant would be limited to 2 TB for all SharePoint sites combined, despite the theoretical 25 TB limit per site. It would be impossible for any one site to use 25 TB. Since OneDrive document libraries are actually SharePoint sites, does that mean that the total storage available in OneDrive for Business for all of the tenant's users is less than 2 TB despite the theoretical 1 TB limit per user?

- No. You have to look 1DRV and SPO as two separated services with different limitations that are not combined.
