Slack Connect guide: work with external organisations
Rather than using email to communicate, you can use Slack Connect to work alongside people from external organisations in a Slack channel or direct message (DM). Read on for an overview of Slack Connect.
Slack Connect for channels
When you need to work as a group, you can use a Slack channel to host up to 250 organisations. Here’s what to bear in mind:
Like other channels in Slack, people can join the channel or be added to it by someone else from their organisation.
People from different organisations working together in channels can send each other DMs. To work in a group DM, everyone in the conversation must be in at least one channel together.
Tip: If you’d like to work with an organisation that’s either not using Slack or not on a paid Slack subscription, you can invite them to try Slack Connect for free.
Channel ownership
Your organisation owns any channels created in your workspace or Enterprise Grid org. When using Slack Connect, only the organisation that owns a channel can do the following:
Shortcuts associated with apps are available to people from other organisations if an app is installed to their workspace. When people take an action from an app shortcut, it will only apply to the account that they’ve connected to the app.
Apps added by another organisation will include that organisation's Slack icon next to the app name. Only people from the organisation that added an app can remove it from a channel.
People in the channel can see messages from bots and apps. They can also exchange messages with an app’s bot user if it’s been added to the channel.
Your organisation’s custom apps and shortcuts can only be used by your organisation, but messages posted by the app or shortcut can be seen by everyone in the channel.
Slack Connect for DMs
If you’d like to communicate one-to-one with someone from an external organisation, you can use a DM. On any Slack subscription, you can start a DM by sending someone an invitation, or by accepting an invitation you've that received.
Using Slack Connect
Here’s what to expect when working with external people in Slack channels and DMs.
When you hover over a channel name or DM, you'll see if any external organisations are in the conversation. You'll also see a banner with the same information when you view the conversation. By default, all your Slack Connect channels and DMs will be organised into the External connectionssection in your sidebar.
Manage Slack Connect
To manage Slack Connect all in once place, hover over More, then click External connections. You'll find the option to send and accept invitations, manage your invitations and more.
View member profiles
Organisations can choose what profile information other organisations can see: either just basic details, such as names and profile photos, or additional details such as statuses and time zones. Profile photos for external people will be marked with their organisation’s Slack icon in the bottom-right corner.
Using custom emoji
You can use your organisation's custom emoji like you would in any other channel or DM. External people can see your organisation’s custom emoji and add them to their own organisation so that they can use the same emoji too.
