Use the TeleMessage connector in the Microsoft 365 compliance center to import and archive Short Messaging Service (SMS) and Multimedia Messaging Service (MMS) data from HK CSL Network. After you set up and configure a connector, it connects to your organization's HK CSL Network once every day and imports SMS and MMS data to mailboxes in Microsoft 365.

After HK CSL Network connector data is stored in user mailboxes, you can apply Microsoft 365 compliance features such as Litigation Hold, Content Search, and Microsoft 365 retention policies to HK CSL data. For example, you can search HK CSL SMS and MMS messages using Content Search or associate the mailbox that contains HK CSL Network data with a custodian in an Advanced eDiscovery case. Using a HK CSL Network connector to import and archive data in Microsoft 365 can help your organization stay compliant with government and regulatory policies.

1. Your organization works with TeleMessage and HK CSL to set up a HK CSL Network connector. For more information, see HK CSL Network Archiver.

2. Once every 24 hours, SMS and MMS messages from your organization’s HK CSL Network are copied to the TeleMessage site.

3. The HK CSL Network connector that you create in the Microsoft 365 compliance center connects to the TeleMessage site every day and transfers the SMS and MMS messages from the previous 24 hours to a secure Azure Storage location in the Microsoft Cloud. The connector also converts the content of SMS and MMS messages to an email message format.

4. The connector imports the mobile communication items to the mailbox of a specific user. A new folder named HK CSL SMS/MMS Network Archiver is created in the specific user's mailbox and the items are imported to it. The connector does this mapping by using the value of the User’s Email address property. Every SMS and MMS message contains this property, which is populated with the email address of every participant of the message.

   In addition to automatic user mapping using the value of the User’s Email address property, you can also implement custom mapping by uploading a CSV mapping file. This mapping file contains the mobile phone number and corresponding Microsoft 365 email address for users in your organization. If you enable both automatic user mapping and custom mapping, for every HK CSL item the connector first looks at the custom mapping file. If it doesn't find a valid Microsoft 365 user that corresponds to a user's mobile phone number, the connector will use the values in the email address property of the item it's trying to import.
