ConvDelete

introduction

Delete conversation

After deleting friend or quitting group, if no need to check history message, you may delete the conversation.

Conversation deletion is not multi-device synchronized by default, you may enable synchronization on IM Console.

Delete conversation will erase history message locally and cloudily and non-recoverable.
