In case you didn't get the email:
Dear AIM user,
We see that you've used AOL Instant Messenger (AIM) in the past, so we wanted to let you know that AIM will be discontinued and will no longer work as of December 15, 2017.
Before December 15, you can continue to use the service. After December 15, you will no longer have access to AIM and your data will be deleted. If you use an @aim.com email address, your email account will not be affected and you will still be able to send and receive email as usual.
We've loved working on AIM for you. From setting the perfect away message to that familiar ring of an incoming chat, AIM will always have a special place in our hearts. As we move forward, all of us at AOL (now Oath) are excited to continue building the next generation of iconic brands and life-changing products for users around the world.
You can visit our FAQ to learn more. Thank you for being an AIM user.
Sincerely, The AOL Instant Messenger team
