You can use the “…” menu on any Microsoft Teams channel message to link the selected message to a Jira issue. This is basically a standalone version of the function that’s also included in creating new issues or adding comments.
Linking a Jira issue to a message / thread will attach all messages & replies to the Jira issue, like you would see if you’d shared the issue from Jira.
How to use it
Click the “…” menu on any Teams message and choose “Link to Jira issue”.
This will bring up a new dialog where you select the issue you want to link.
If you selected a reply of a conversation thread, you will be able to choose if you want to link the whole thread or only the selected message. Linking only the selected message will hide previous replies and the main message in Jira.
You can also choose who should be notified of this new link.
