It can be really aggravating for Not being able to send messages on Microsoft Teams. Perhaps your teacher, mate, or project manager is expecting you to respond to a critical chat message. Teams, on the other hand, have suddenly chosen to undermine you.
Microsoft Teams may occasionally display issues such as:
1. Because you are not a chat member, you are unable to send messages.
2. This channel can only be used by owners to send messages.
3. The message was not sent.
What to Do If Microsoft Teams Won’t Send Your Messages
Quick Note: If you’re having trouble sending messages to your team’s separate channel, it’s possible that there’s a larger problem. Look at the Office365 health status to see if there’s anything there about Teams messaging problems.
If You’re Getting Permission or Access Related Errors
If Teams was unable to send your message because you are not a part of that chat or channel, please contact the owner of that chat or channel. They most likely accept strong authorization settings that prevent external parties from sending messages.
Check in the Teams Admin Center with your IT admin to see if the Teams Messaging policy has been assigned to your user account.
Ensure you’ve been invited to the appropriate chat or channel. Then request that they allow you to utilize the chat and send messages to other conversation members.
