Mailbox chat - You can chat with friends in the mailbox when QQ is not open.

As long as you can use QQ email, you can check the online status and chat with the other party's QQ in the email;

You can view the other party's online status in QQ email, but there is no QQ login online status after logging into the email;

Since there is no QQ online status login, using the chat function in QQ email will not increase your online time and积分;

If you do not initiate a chat actively, QQ email will not receive any chat messages from QQ;

After initiating a chat, the other party must use QQ 2007 official version or above to reply, and we will give a prompt when the other party's QQ version is not supported;

If the other party is not online, the conversation between you and them through QQ email will become an offline message, which they will see when they come online next time.
