Title: Users' OneDrive for Business storage limits are lower than expected
User Impact: Users' OneDrive for Business storage limits are lower than expected.
More info: For any quota which exceeds the 1TB storage, users may only be able to see their content in read-only mode.
Whilst in read-only mode, users can access their content in OneDrive for Business, but are unable to make changes.
For users experiencing impact with custom quotas, we have provided an interim solution below while we work on developing a more robust solution. This solution was provided in an earlier communication and was not functioning properly, however, we have since addressed the issue.
We recommend admins attempt to manually set the quota for individual users. Instructions can be found here: https://docs.microsoft.com/en-us/onedrive/change-user-storage
We're expecting some users with non-custom quotas may see a delay in mitigation, and if necessary, they can expedite this process by navigating to their OneDrive for Business account via the web.
While we understand this may not be a viable option for all organizations, we're committed to providing all potential solutions to our customers.
Current status: The deployment is nearing completion, and we expect to begin post deployment validations by the end of day, September 2, 2021. Once the fix has taken full effect, both users with custom and non-custom quotas can manually trigger a refresh through various actions within OneDrive to resolve this issue. For example, by accessing their OneDrive for Business account from the web or selecting a file.
Our automatic refresh activity is on schedule to be completed and initiated by end of day, September 3, 2021.
We understand how impacting this issue has on your organization and we want to assure you that we are treating the issue with the utmost priority. We appreciate your patience and will continue to update the Service Health Dashboard daily.
Scope of impact: This issue affects a large subset of users worldwide, who have a storage quota that exceeds 1TB.
Preliminary root cause: A misconfiguration resulted in our internal systems not recognizing user licenses and reverting the storage quota limit to the default settings of 1TB.
