MIT Slack Enterprise Grid Landing Page

On this page:


Slack is a messaging and collaboration tool for teams, groups and individuals. Members of a workspace in Slack can direct message individuals or create conversation channels for topics, projects and groups. Conversation channels can be visible to the whole workspace or be set up as private channels accessible by invitation only. There you can share files and connect slack to Dropbox, Google Drive, Zoom, Github, Webex and many more applications and services. You also have your own Slackbot that allows you to store notes, set reminders and get answers to your questions about using Slack.

All MIT faculty, staff and students are eligible to request a workspace. Affiliates are eligible to participate in workspaces. Non-MIT members can be invited as a Guest. (Invite New Members)

MIT's Slack Enterprise Grid

MIT's Slack Enterprise grid, or Organization (Org for short) is comprised of multiple interconnected workspaces across MIT. Departments, labs, centers, and groups can each have their own dedicated workspaces with customized channels, permissions and access controls. All the workspaces in the MIT Slack Org use the same single sign-on Touchstone Authentication system, search, direct messaging, and directory. You only need to login once to access all your MIT Slack Org workspaces.


Workspaces are made up of channels where team members can communicate and work together. Each workspace has its own administrators who can control access and settings for the workspace. All the workspaces in MIT's org share directory service, search and direct messaging functionality.

Access MIT's Slack Enterprise Grid at, where you can learn about getting started with MIT's Slack Enterprise Grid.

Request a Workspace

MIT faculty, staff, affiliates and students are eligible to request a workspace by emailing the following to

  • Workspace name
  • URL must start with “mit-“ and not exceed 21 characters, e.g., “mit-example-workspace”
  • Short workspace description
  • List of workspace owners (kerberos usernames)

The Service Desk will notify you when it has been created. Then you can begin customizing your workspace settings and inviting users. For details, see Administer Your Workspace.

Please be aware that while guests are welcome on MIT Slack, it's a tool intended to be used primarily by the MIT community. Thus, if the number of guests exceeds 40% of the total membership, users should not request a workspace.

An alternative solution is Slack Connect; which allows members of the MIT community to invite guests to channels on their workspace without adding them to workspace membership.

Users can also utilize free Slack workspaces not associated with the MIT Slack Grid.

If you have questions about this guidance, please contact the Service Desk.

Do not Disturb (snooze)

MIT-IST Slack goes into "Do Not Disturb" by default from 10PM to 8AM. When "Do Not Disturb" is in effect, Slack will not send you desktop, mobile, or email notifications. Team members who try to send you messages during your "Do Not Disturb" hours will be warned you won't be notified unless they take a further step to click on a link indicating that it is urgent. For information on how to disable "Do Not Disturb" or customize your hours, see:
