How to Increase Maximum OneDrive Storage Limit in Microsoft 365

Product: Microsoft 365 / OneDrive
Device & OS: not provided
Scenario: An organization needs to expand user cloud storage capacity beyond the default 1 TB or 5 TB allocation provided by their Microsoft 365 licenses.
Observed behavior: The organization seeks clarity on the requirements, license types, and administrative steps necessary to request up to 25 TB of OneDrive storage without incurring extra costs.

Before you start

Before requesting a storage increase, verify that your organization holds at least five eligible Microsoft 365 licenses (such as OneDrive Plan 2) and that the specific user has already utilized at least 90% of their current 5 TB OneDrive allocation.

Solution 1Recommended

Request a Storage Increase to 25 TB from Microsoft Support

Administrators can request an increase from 5 TB to 25 TB once an eligible user has reached 90% of their current storage capacity.

This storage expansion requires backend approval from Microsoft and is only available for organizations meeting specific enterprise licensing criteria. Individual users cannot perform this action.

Verify user usage

Check the user's current OneDrive capacity to ensure they have already used at least 90% of their 5 TB allocation.

Check organizational licenses

Confirm your organization has a minimum of five licenses that include OneDrive Plan 2, and that the target user is assigned one of these licenses.

Access Microsoft 365 Admin Center

Open a support case

Navigate to 'Support' > 'Help & support', and submit a new ticket requesting a OneDrive storage limit increase to 25 TB for the specific user.

Request a Storage Increase to 25 TB from Microsoft Support

No Additional Cost: The 25 TB allocation is included at no additional cost, provided your organization meets the licensing requirements and the user has reached the usage threshold.

Solution 2

Increase Default Storage from 1 TB to 5 TB

If users currently have the baseline 1 TB, administrators can independently increase the default limit to 5 TB via the SharePoint admin center.

Frequently Asked Questions

What happens if a user needs more than 25 TB of OneDrive storage?

If a user exceeds the maximum 25 TB limit, Microsoft typically allocates additional storage by providing 25 TB SharePoint team sites to the individual user, rather than increasing the capacity of the single OneDrive account.

Do I have to pay extra to increase my storage from 5 TB to 25 TB?

No, if your organization has the required eligible licenses (such as Office 365 E3, E5, or equivalent Government licenses) and the user meets the 90% usage threshold, the increase to 25 TB is provided by Microsoft at no additional cost.

Can a regular user request the 25 TB storage increase themselves?

No, a regular user cannot request this storage limit increase directly. An organization's global or SharePoint administrator must open a support case with Microsoft to apply the storage expansion.
