The systems team has completed its response, and we have confirmed that no new misdetections are occurring at this time. The period during which this issue occurred is as follows:
From approximately 12:09 PM on January 8, 2026, to 1:43 PM on January 14, 2026 (JST)
Regarding the files that were misdetected and had their public links deleted by the Auto Remediation Policies, we are planning to restore the same level of access permissions (Internal/Organization-wide only) from the system side.
Please note that while this recovery will restore the organization-wide access permissions to their original state, the URLs for the public links will be changed. There will be no issues when accessing files through SharePoint folders. However, if you use direct public URLs, please re-share the newly generated URLs.
We will provide a further update on this dashboard once the recovery process is complete.
If you are in a hurry to restore a file's public link, we kindly ask that you manually re-configure the organization-wide sharing settings yourself.
We sincerely apologize for the continued inconvenience.
