Use DataParser from 17a-4 LLC to import and archive data from the Slack platform to user mailboxes in your Microsoft 365 organization. DataParser includes a Slack connector that's configured to capture items from a third-party data source and import those items to Microsoft 365. The Slack DataParser connector converts Slack data to an email message format and then imports those items to user mailboxes in Microsoft 365.
After you store Slack data in user mailboxes, you can apply Microsoft Purview features such as Litigation Hold, eDiscovery, retention policies and retention labels, and communication compliance. By using a Slack connector to import and archive data in Microsoft 365, you help your organization stay compliant with government and regulatory policies.
Overview of archiving Slack data
The following overview explains the process of using a data connector to archive Slack data in Microsoft 365.

Your organization works with 17a-4 to set up and configure the Slack DataParser.
The DataParser regularly collects Slack items and converts the content of a message to an email message format.
You create the Slack DataParser connector in the Microsoft Purview portal. The connector connects to DataParser and transfers the messages to a secure Azure Storage location in the Microsoft cloud.
The connector creates a subfolder in the Inbox folder named Slack DataParser in the user mailboxes and imports the Slack items to that folder. The connector uses the value of the Email property to determine which mailbox to import items to. Every Slack item contains this property, which is populated with the email address of every participant.
Before you set up a connector
Important
All partner third-party data connector configurations require a provisioned service principal for the partner application. This requirement isn't applicable for native Microsoft third-pary data connector configurations.
To provision a service principal using PowerShell, see Provision a service principal for partner third-party data connectors.
Create a DataParser account for Microsoft connectors. To do this, contact 17a-4 LLC. You need to sign in to this account when you create the connector in Step 1.
Assign the Data Connector Admin role to the user who creates the Slack DataParser connector in Step 1 (and completes it in Step 3). This role is required to add connectors on the Data connectors page in the Microsoft Purview portal. Multiple role groups include this role by default. For a list of these role groups, see Roles in Microsoft Defender for Office 365 and Microsoft Purview compliance. Alternatively, an admin in your organization can create a custom role group, assign the Data Connector Admin role, and add the appropriate users as members. For instructions, see:
This 17a-4 data connector is available in GCC environments in the Microsoft 365 US Government cloud. Third-party applications and services might involve storing, transmitting, and processing your organization's customer data on third-party systems that are outside of the Microsoft 365 infrastructure. Therefore, these systems aren't covered by the Microsoft Purview and data protection commitments. Microsoft makes no representation that use of this product to connect to third-party applications implies that those third-party applications are FEDRAMP compliant.
Step 1: Set up a Slack DataParser connector
Create a 17a-4 connector for Slack data in the Microsoft Purview portal.
- Sign in to the Microsoft Purview portal.
- Select Settings > Data connectors.
- Select My connectors, then select Add connector.
- Choose Slack DataParser from the list.

Step 2: Configure the Slack DataParser connector
Work with 17a-4 Support to configure the Slack DataParser connector.
Step 3: Map users
The Slack DataParser connector automatically maps users to their Microsoft 365 email addresses before importing data to Microsoft 365.
Step 4: Monitor the Slack DataParser connector
After you create a Slack DataParser connector, you can view the connector status in the Microsoft Purview portal.
- Sign in to the Microsoft Purview portal.
- Select Settings > Data connectors.
- Select My connectors, then select the Slack DataParser connector that you created to display the flyout page, which contains the properties and information about the connector.
- Under Connector status with source, select the Download log link to open (or save) the status log for the connector. This log contains information about the data that's been imported to the Microsoft cloud. For more information, see View admin logs for data connectors.
