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?
- What is the action that you are looking for that DLP needs to act upon?
Is it on saving the data on a specific location? or sending the data to an recipient?vicwingsingGrouping all possible letters and numbers into a NOT group worked. I'm receiving the alerts now.
- It's sending incident reports to an administrator. So far, nothing received, so it's not working. Other DLP policies which include a policy tip are working as expected but the conditions for those policies are not trying to match the "document property is" condition with a null value. So, I think the problem is either 1) I have the wrong syntax for matching null values or 2) null values are not supported.
- Trying this too: '-ComplianceTag:*'
