Conversations among multiple participants for collaboration and communication in Teams
Hi HONAS,
I'm RY and I'm happy to help you today! Sorry to hear that you are having issue with Teams chat but I'd be glad to help you to sort this out.
With this kind of concern, you just need to coordinate this with your IT Administrator as they have permission to manage Teams account within your organization.
Please take note that this is a public user-to-user forum. We're users just like you helping other users and we do not work for Microsoft nor have access to any user accounts or information.
Thank you!
Regards,
RY
