WebDAV store &1 does not support legal hold

What causes this issue?

The legal hold is to be propagated for a collection or resource to which
an archive store is assigned which does not fulfill all functional
requirements. Specifically, the archive store is not able to propagate a
legal hold on lower-level collections and resist deletion attempts. Thus
data which, from the LEGAL HOLD Management viewpoint, ought to be
protected, is at risk of being deleted.
