DLP rule - Document Property is: 'ComplianceTag:\0'
Is an expression like the one below supported by the "Document Property Is" condition when setting a DLP Policy in Purview? I'm trying to set a rule that applies a DLP alert to files in SharePoint that do not have a retention label applied to them. Would using the null character regex work for this? Document Property is: 'ComplianceTag:\0' Alternatively, is it possible to set a rule when a document property does NOT contain something?
