The problem

A Slack user selects Confirm on a chat invitation from a Microsoft Teams user, but nothing happens. No channel for the Teams user appears in Slack.

Why it happens

The TeamsLink app creates a private Slack channel for each connection. If the Slack workspace doesn't allow members to create private channels, the connection fails without showing an error.

How to fix it

1. In Teams: the Teams user clears the chat history in the group chat that was created for the Slack user. This removes what is left over from the failed attempt.
   
2. In Slack: the Slack administrator allows members to create private channels. See Slack Administrators: Preparing Your Workspace for Teams Chat.
3. In Slack: the Slack user selects Confirm on the invitation again.

If the channel still doesn't appear, contact CallHarbor Support.
