When mapping crawled properties to managed properties (e.g. RefinableString) in the SharePoint Admin Center the mapping is not displayed after changes are saved. We were able to confirm that the mapping is persisted and managed properties are populated with values from added crawled properties, even if the Search Schema UI doesn’t show the mapping.
While this does not affect the functionality of MetaShare directly, we are getting reports and questions about the issue from MetaShare administrators. We have reported our findings to Microsoft but they reported that no issue was found. We continue monitoring the situation.
Update: 18 June 2026
Microsoft has now acknowledged the issue and it can be followed in Microsoft 365 admin center (issue SP1393483)
