On Enterprise Grid, you can use Slack Connect with free teams to make working with people outside your company more seamless. When this setting is enabled, teams on a free plan can join channels they’re invited to in your org without having to upgrade or start a free trial. 

Manage connections with free teams

By default, the setting to use Slack Connect with free teams is disabled, but Org Owners and Org Admins can manage this from the admin dashboard. If enabled, this setting will only affect future invitations sent from your organization.

What to expect for free teams

Below is what free teams can expect when working with your company in Slack Connect channels:

• Messages won’t count toward the message visibility limit.
• Uploaded files will count toward the file storage limit. All files will be accessible in a Slack Connect channel, even if the storage limit is reached.
• Channel members can start and join huddles, record audio and video clips, add and use apps, and use published workflows (but cannot create their own).
• People from free teams can join Slack Connect channels they’re invited to, but cannot send invitations to work with other organizations.
