Hi @sujeetnishad,


I'm afraid you cannot deeplink the chat to a guest user.  

Referring to documentation supported user ID is AAD UserPrincipalName, but guest AAD UPN is not working.


Is your requirement to open a chat exactly to a guest user in your tenant?

Yes, you are right!
Yes, we need to open the guest user chat on click for which we are using the deep link!
This is still a problem in 2023
