Issue Status: RESOLVED

Microsoft Reference: 2506030050004170247

Issue Description: We are currently aware of an issue where OneDrive storage quotas, as defined by user licence allocations, have been enforced across the platform. This has resulted in users who are exceeding their allocated quota having their OneDrive access restricted. Affected users may find that their OneDrive is effectively disabled, preventing normal use.

Final Update: 10/06/2025 10:00:00 AM: Following an uplift to affected users we have received no further tickets regarding users being over their quota. This incident will now be resolved and new tickets will be dealt with on a case by case basis.

Please note, this is a temporary measure and discussions are ongoing with Microsoft to agree a date in the future where Microsoft will re-enable this job and users without the relevant licences will be reduced to 2GB again. We strongly advise that organisations use this time to reduce their storage utilised in OneDrive as a matter of urgency, or to purchase additional licenses to allow for a 1TB quota. Users in an Enhanced Organisation are unaffected by this issue since the Microsoft 365 E3 provides users with 1TB by default. Standard Organisations utilising the Microsoft 365 F3 will be given 2GB by default unless they have been assigned to a user policy with Apps For Enterprise assigned which will automatically provide an uplift to 1TB.

NOTE: The toggle for this feature is not available in the NHSmail Portal for Apps For Enterprise and cannot be toggled off. The toggle SharePoint (OneDrive) under the base licence will have a null effect.

Microsoft engineers, working alongside our internal teams, have identified that a long-overdue sync job ran and applied OneDrive storage limits based on the licensing policies set for each user. As the sync job had not been executed for some time, many users had unknowingly exceeded their quotas. As a result, OneDrive accounts for those users were disabled. When this occurs, users are unable to upload or sync files, and existing files may become read-only.

While the sync job performed as designed, we fully acknowledge the disruption this has caused. We are actively working with Microsoft and NHS England to explore potential mitigations, including whether a grace period can be implemented to allow users time to reduce their storage usage before enforcement resumes.

If you are impacted, you will receive a notification in the coming days. Affected users are expected to reduce their storage to fall within the permitted quota or purchase an Apps for Enterprise licence. Full details of your storage allocation can be found here:
