I have a process for extracting email addresses from one of our systems. We want to add these as contacts to Dynamics 365 Customer Insights - Journeys. We then want to clean up the list by removing invalid emails. However we want to do this in a way that they won't be imported again. My plan was to set these contacts to inactive.
There is a duplicate detection rule set up for contacts when there is an exact match on email. This doesn't include a filter on status, so I would assume it would apply for active and inactive contacts. However, when I perform an import, it only detects a duplicate for active contacts.
Any suggestion how to achieve this? My knowledge of Dynamics 365 is basic.
