ERROR_CLOUD_FILE_PROPERTY_VERSION_NOT_SUPPORTED
The reader and the stored property format do not agree on a version
ERROR_CLOUD_FILE_PROPERTY_VERSION_NOT_SUPPORTED indicates a format-compatibility problem in the cloud-file property store. It commonly matters during provider or operating-system transitions, when placeholders created under one implementation are opened by code that does not understand the stored version. It is distinct from generic corruption because the property may be structurally valid for another supported version.
Record the Windows build, provider build, sync-root identity, and first affected placeholder. Test whether old placeholders fail while newly created ones work, or the reverse. Provider upgrades should include an explicit migration or recreation path and must remain able to map the placeholder FileIdentity to the authoritative remote object. Blindly deleting versioned metadata can make rollback or unsynchronized-change recovery impossible.
What to inspect
- Compare provider and OS versions between healthy and failing machines.
- Determine whether the issue affects only placeholders created before or after an upgrade.
- Preserve FileIdentity and local-change state before migration or recreation.
