Microsoft OneDrive: New policies to control file exclusions

Microsoft is introducing new OneDrive policies allowing users to manage their own file-level exclusions by default, while admins can restrict this via policies. From October 5, 2026, .db-wal files will be excluded from sync by default. Folder-level exclusions are not included in this update. Microsoft is introducing two new OneDrive policies for file-level exclusions on Windows and macOS. Today, commercial users can view file exclusions configured by their organization, but they cannot add or remove exclusions. After this rollout, users will be able to manage their own file-level exclusions by default. This self-service capability applies only to user-managed exclusions. Users will not be able to remove exclusions configured by administrators through Group Policy or other policy management methods. To help organizations maintain control over this experience, Microsoft is introducing the following policies: DisableChangesToODIgnoreList: Prevents users from managing file-level exclusions and hides the self-service experience. DisableDefaultODIgnoreList: Disables Microsoft’s built-in default file exclusion list when organizations require excluded file types to sync. Additionally, beginning October 5, 2026, Microsoft will add the .db-wal file type to the default OneDrive exclusion list. .db-wal files are temporary database files that can change frequently and are generally useful only with their associated database. Excluding new .db-wal files reduces unnecessary sync activity and avoids uploading transient application data. Folder-level self-service exclusion controls are not included in this release and will be communicated separately. Rollout schedule General Availability (Worldwide): Beginning in early August 2026 and expected to complete in early September 2026 Additional change: On October 5, 2026, .db-wal files will be added to OneDrive’s default exclusion list.
