Use the TeleMessage connector in the Microsoft 365 compliance center to import and archive WhatsApp calls, chats, attachments, files, and deleted messages. After you set up and configure a connector, it connects to your organization's TeleMessage account once every day, and imports the mobile communication of employees using the TeleMessage WhatsApp Phone Archiver or TeleMessage WhatsApp Cloud Archiver to mailboxes in Microsoft 365.

After WhatsApp 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 Verizon data. For example, you can search WhatsApp messages using Content Search or associate the mailbox that contains WhatsApp messages with a custodian in an Advanced eDiscovery case. Using a WhatsApp 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 to set up a WhatsApp Archiver connector. For more information, see WhatsApp Archiver.

2. Once every 24 hours, your organization’s WhatsApp data is copied to the TeleMessage site.

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

4. The connector imports WhatsApp data to the mailbox of a specific user. A new folder named WhatsApp 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 WhatsApp 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 WhatsApp item the connector first looks at 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. If the connector doesn't find a valid Microsoft 365 user in either the custom mapping file or in the email address property of the WhatsApp item, the item won't be imported.
