Use Content Search to search third-party data imported by a custom partner connector
You can use the Content search eDiscovery tool in the Microsoft Purview compliance portal to search for items imported to mailboxes in Microsoft 365 from a third-party data source. You can create a query to search all imported third-party data items or you can create a query to search specific third-party data items. Also, you can also create a query-based retention policy or a query-based eDiscovery hold to preserve third-party data.
For more information about working with a partner to import third-party data and a list of the third-party data types that you can import to Microsoft 365, see Work with a partner to archive third-party data in Office 365.
Important
The guidance in this article only applies to third-party data that was imported by a custom partner connector. This article doesn't apply to third-party data that is imported by using the third-party data connectors in the Microsoft compliance center.

Creating a query to search all third-party data
To search (or place on hold) any type of third-party data that you've imported to Office 365, you can use the kind:externaldata message property-value pair in the keyword box for a Content Search or when creating a query-based hold. For example, to search for items imported from any third-party data source and contain the word "contoso" in the Subject property of the imported item, you would use the following query:
kind:externaldata AND subject:contoso
The previous keyword query example includes the subject property. For a list of other properties for third-party data items that can include in a keyword query, see the "More information" section in Work with a partner to archive third-party data in Office 365.
When creating queries to search and hold third-party data, you can also use conditions to narrow the search results. For more information about creating Content Search queries, see Keyword queries and search conditions for Content Search.
Creating a query to search specific types of third-party data
Instead of searching all types of third-party data, you can create queries that only search for a specify type of third-party data by using the following message property: value pair in the keyword box for a Content Search:
itemclass:ipm.externaldata.<third-party data type>*
For example, to search Facebook data that contains the word "contoso" in the Subject property, you would use the following query:
itemclass:ipm.externaldata.Facebook* AND subject:contoso
The following table lists the third-party data types that you can search, and the value to use for the itemclass: message property to specifically search for that type of third-party data. The query syntax isn't case-sensitive.
