 Azure Communication Services stores chat threads according to the [data retention policy](/purview/create-retention-policies) in effect when the thread is created. You can update the retention policy if needed during the retention time period you set. After you delete a chat thread (by policy or by a Delete API request), it can't be retrieved.

 You can choose between indefinite thread retention, automatic deletion between 30 and 90 days via the retention policy on the [Create Chat Thread API](/rest/api/communication/chat/chat/create-chat-thread), or immediate deletion using the APIs [Delete Chat Message](/rest/api/communication/chat/chat-thread/delete-chat-message) or [Delete Chat Thread](/rest/api/communication/chat/chat/delete-chat-thread). 
 
 Any thread created before the new retention policy isn't affected unless you specifically change the policy for that thread. If you submit a support request for a deleted chat thread more than 30 days after the retention policy deleted that thread, it can no longer be retrieved and no information about that thread is available. If needed, [open a support ticket](/azure/azure-portal/supportability/how-to-create-azure-support-request) as quickly as possible within the 30 day window after you create a thread so we can assist you.
