I'm trying to open a chat or start a call on Microsoft Teams throw Deep Links.

I used these Deep Links:

https://teams.microsoft.com/l/chat/0/0?users=joe@contoso.com&message=hello

https://teams.microsoft.com/l/call/0/0?users=joe@contoso.com

If I test them with the test Account 'joe@contoso.com' they work fine instead where I use a real email I get error.

I get ' We've started your group chat but couldn't add xxx@yyy.com ' error when I try to open the Chat.

I get ' There's a problem with the link - Try contacting the person who shared it. ' error when I try to start a call.

(I'm using the free version/account subscription of Microsoft Teams)

Can you help me? Thanks.
