To ensure we're aligned, and I can provide you with accurate information, I’ll need your cooperation to confirm a few details first:
1. Are you using a personal account (e.g., outlook.com, hotmail.com), an educational account (e.g., @edu_), or a business account (e.g., @yourcompany.com)?
2. Are you encountering an error when creating a new chat in Teams like the image bellow? (Please share the full error message or a screenshot so I can better understand and address the issue.)
3. Is this issue happening with a regular chat in Teams or a meeting chat?
4. Are you trying to chat with someone inside or outside your organization?
5. Is this also happening to other users in your organization?
6. Are you able to send messages in existing chats, or is all chat functionality affected?
Besides, I also found some related Microsoft Articles to support you, please take a look to see if it's what you need:
