iMessage sync with computer after deleting If you send a text on your iphone and then immediately delete it while the synced Mac computer and ipad is off/not connected to Wifi, will the messages still appear in chat on the Mac when you connect it?
When the iMessage is send, then its sent.


So when you activate iMessage again on this other "Computer" (Mac, iPad, iPhone), then it appears. It could be that after a certain amount of days, the message is deleted from Apples Server.
