This topic describes when Alibaba Cloud deletes queues that are not used for a long period of time.

No, Alibaba Cloud will not delete your MNS queues if your Alibaba Cloud account has a sufficient balance, regardless of how long the queues have been in the inactive state. However, if MNS is suspended due to reasons such as overdue payments, Alibaba Cloud will delete all queues and topics under your Alibaba Cloud account.
