Sharing channel links makes it easy for others to find and join channels. To share a link to a channel, type ~ into the message text box, then select the channel you want to link to. If you’re a member of multiple teams, only channels for the current team are listed.
Alternatively, you can select the View info icon in the top right corner of the screen to access additional channel management options, including a Copy Link option you can share with others.
Sharing message links displays a preview of the message in the post. To share links to messages in Mattermost, select the More icon next to a message, then select Copy Link.
Paste the link into a message to share the image link with others. Sharing links to messages generates a preview of the message.
You can also hover over an image and select the icon in the top right corner.
The timestamp next to the username of any message is also a permanent link to that conversation.
Long press a message, and then tap Copy Link to copy the link to the clipboard. Long press to paste the link as a message or reply. Sharing links to messages generates a preview of the message.
Message previews respect channel membership permissions, so they’re only visible to users who have access to the original message. If the link is to a message in a public channel, any member of the team can see the message preview. If the link is to a message in a private channel or direct message, only members in that channel can see the message preview.
