@sAntosh3436 There are few nuances to this and have you tried to further narrow it down? For instance
Does message sending fails from all clients i.e desktop, web and mobile?
Are these messages are sent to other teams or sfb users? are these internal or federated users where message sending fails?
You can also begin investigation by looking into client logs by pressing ctrl+alt+shift+1 after a repro or capturing a fiddler trace as well?

In addition, have you tried to change networks and test if message sending/receiving works? Be sure to whitelist Teams urls & Ips if there are proxy,firewalls on the network.
