Why won't my iMessage work with only one contact in my phone all my other iMessages send and they just got an iphone but all their iMessages are sending also. I've tried restarting my phone, deleting messages, contact, restarting network

Just had this issue and fixed it.

Messages>Preferences>[yourAccount]>Enable this account Uncheck this.

Facetime>Preferences>Turn OFF the switch and turn back ON.

II'm having the same problem!!

Worked! Apple support response was useless but this restored iMessage to the one contact without losing message history. Thx!

How exactly do you do this on your iPhone? I cannot find the preferences tab under messages. Please help!

Does this contact have an iDevice and is iMessage active on that?

Same problem

My message still isn't sending I don't know what's going on so can someone help me.

I have the same issue as the OP. iMessage will not work with one contact only - my husband. I have tried all the troubleshooting steps suggested to no avail. This seems to be a real bug dating back a number of years based on the posts in the forum. It would be very much appreciated if Apple would look into this and come out with a proper fix.

I sent my dad a text while I was on the phone yesterday. I knew it would go thru as a text messag, but it seems to have triggered something and now all of our messages are texts. Nothing will go through iMessage even though iMessage is working with everyone else. I have tried all of the solutions I can find online (except deleting the messages) and nothing works. If I backup my phone, does it save all our messages? I don't want to delete them for personal reasons.

Make sure that neither user has the other one blocked. This was the case on my girl friends phone. She swears she didn't block me.LOL She had other numbers blocked mysteriously too. Go to settings then messages checked for blocked numbers, under MMS/SMS, both phones. Note I'm not talking about the block on the contact pages, it's different. Good luck.

I had this issue with just one contact, and the solution was that they had removed their email address from their iMessage settings, so I had to use their phone number for sending them iMessages.

I was easily able to see this and fix it on the Mac, not sure how one would do this on the iPhone etc.

I am also having this problem - I have read all the forums and went to the apple store, absolutely nothing has worked. if anyone has an updated answer please let me know ...

I had the same problem and this is what worked for me:

1. Turn iMessage off

2. Reboot the iPhone

3. Go to messages and delete the thread of that persons messages (I didn't back anything up because I just wanted it fixed)

4. Make sure there aren't any group messages with that contact.

5. Write down their contact info

6. Delete that contact

7. Compose a new message and manually enter the phone number.

8. I sent 2 messages that were green and received one back (that said hers was also green) but on the THIRD response, my message was blue.

9. Re-add the contact

Hope this works!!

I had same exact issue and did everything I read from web short of reseting network or restoring phone. I had issue with sending message to husbands iPhone, my attempts to send messages from either my iPhone or iPad would not go by iMessage but mac would send without problem. I looked at his phone, and in his setting for messages his setting to initiate messages had icloud checked instead of iPhone. I placed check to initiate messages from iPhone, then sent a message to my phone and all worked fine since. Not sure why that made a difference but it did.

Niether do I
