The only way to delete an i. Message from both sides is to have direct access to both i, and message accounts. In that case, you need to go through the process of deleting the message on a device connected to each account. When that is done, the i. Message is permanently removed on both sides.
While I was researching we ran into the question “When I delete a iMessage from a conversation it gets deleted?”.
No, each device has a local copy of the message that stays until it is deletes from that device. I think Apple should modify that….
My experience is you cannot actually delete an i. Message once and have it delete elsewhere. You can only delete the local cached copy of a message to suppress it being showed/stored on that one device. If you turn off i. Message and turn it back on, you will see the messages from i. Cloud come back whether you deleted a message or not.
Does deleting a message from the Messages app on iOS remove it?
