[fan_charlie]

hi

i create a deeplink to chat at teams tab webapp as follows:

(1) <a href="https://teams.microsoft.com/l/chat/0/0?users=test@example.com">To Chat</a>

it is not working. 

when i change a link as follows:

(2) <a target="_blank" href="https://teams.microsoft.com/l/chat/0/0?users=test@example.com">To Chat</a>

it is working.

i want to use a link without target="_blank". who can help me?

I'm a bit confused, can you screenshot what you are trying to do and why _blank doesn't accomplish your needs? Thanks!

thank you for your reply

i did follows:

(1) make a webpage with two deeplink to a chat.
first deeplink(with target="_blank") first deeplink
second deeplink(without target="_blank") second deeplink
(2) create this webapp to teams channel tab names 'myapp' with url like as https://example.com
(3) clicked 'myapp' tab, the webpage will be show in teams and two deeplink can clickable
(4) clicked first deeplink(with target="_blank"), a browser will started outside teams and show a page as screen1
(5) clicked the last link, teams chat will be start.
(6) clicked second deeplink(without target="_blank"), theams can be show a page as screen2
(7) clicked the last link, teams chat can not be start(no any response).

our client don't like to start a chat must be open a new tab throught a browser.
they want do anythin inside teams only.

is any way to resolve this?
