I mistakenly closed a direct message window on Slack. How can I re-open it?
I clicked here:
On latest versions of Slack desktop app, it's the DMs
icon on sidebar that shows all recent direct messages.
Here you can search for the chat with that person who's name / alias your'e unable to remember after having closed the chat.
Just re-open a direct message with the same person. The conversation history will still be there.
On the same screen where you can start (or find) a direct conversation, there should be a list of recently active conversations. If you've forgotten which conversation you've closed you should be able to find it there.
Press Ctrl+K, enter the name of your contact and it should appear on the sidebar again.
In case you want to reopen a conversation with multiple participants... I managed to do it by simply searching for some words I remembered from that conversation - apparently the search goes through removed conversations also.
Just beside Direct Message you see three dots, click on it then click on Browse DMs, then find for the person you removed click on it :)
