Can I view chat history for deleted users or deleted chat rooms?

Why am I seeing the “User Limit Exceeded” message in Output Messenger?

The User Limit Exceeded message appears when the number of connected users exceeds the number of licensed users available on your server. Please verify whether the connected user count has exceeded your license limit by right-clicking the User List to sort users by name and checking the total count displayed in the Output Messenger client.

How do push notifications work in Output Messenger?

Push notifications are sent immediately when a user is logged in on a single device. If the user is logged in on multiple devices, notifications are sent at intervals, and no push notification is sent if the message has already been viewed on any of the logged-in devices.

Can I configure multiple static IP addresses in Output Messenger?

Yes. Output Messenger allows you to configure multiple static IP addresses by entering them in the IP address field separated by a semicolon (;), for example: 192.168.2.1;202.205.206.21. The client will automatically use the appropriate IP address based on the network it is connected to.
