All my friends and I have our iMessage Caller IDs set to our email addresses on our phones and other devices. My question is, if I've started an iMessage to a friend via our email addresses and in the middle of the conversation I decide to turn off iMessage for a little while, when I decide to turn iMessage back on, will it deliver the messages that my friend has sent me during my iMessage hiatus? I guess I already know that answer to my own question, and that is, "no". My brother and I have tried it and the only indication that I never will receive his message is that on his end in iMessage it will never say "Delivered" underneath the message. It will be blue, indicating a connection with an iMessage participant, but it will never say delivered and I will never receive it when I turn on iMessage again. It seems that it is lost in space forever.....on Apple's servers? This problem only occurs when using iMessage to contact a recipient using their email address and not their phone number, since the message will be resent as an SMS if the recipient has iMessage off. Thoughts?
