Use a TeleMessage connector in the Microsoft 365 compliance center to import and archive Short Messaging Service (SMS) messages and voice calls from the O2 mobile network. After you set up and configure a connector, it connects to your organization's O2 Network once every day, and imports SMS and voice calls to mailboxes in Microsoft 365.

After SMS messages and voice calls are stored in user mailboxes, you can apply Microsoft 365 compliance features such as Litigation Hold, Content Search, and Microsoft 365 retention policies to O2 Network data. For example, you can search O2 Network SMS messages and voice calls using Content Search or associate the mailbox that contains O2 Network data with a custodian in an Advanced eDiscovery case. Using an O2 Network connector to import and archive data in Microsoft 365 can help your organization stay compliant with government and regulatory policies.

Your organization works with TeleMessage and O2 to set up an O2 Network connector. For more information, see O2 Network Archiver.
Once every 24 hours, SMS messages and voice calls from your organization’s O2 Network are copied to the TeleMessage site.
The O2 Network connector that you create in the Microsoft 365 compliance center connects to the TeleMessage site every day and transfers the SMS messages and voice calls from the previous 24 hours to a secure Azure Storage location in the Microsoft Cloud. The connector also converts the content of SMS messages and voice calls to an email message format.
The connector imports the mobile communication items to the mailbox of specific users. A new folder named O2 SMS and Voice Network Archiver is created in a 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 message and voice call 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 define a 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 O2 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 O2 item, the item won't be imported.
