OneDrive and SharePoint for Slack

If you use Microsoft OneDrive or SharePoint to host and manage your files in the cloud, you can install the OneDrive and SharePoint app to create, share and view your files right from Slack.

What to expect

  • Office 365 accounts (SharePoint Online, OneDrive for Business, Office 365 Enterprise) and non-Enterprise Microsoft accounts (OneDrive and OneDrive Basic) can use the OneDrive and SharePoint Slack app.
  • On-premises SharePoint installations or Office 365 plans that are hosted on a Microsoft national cloud deployment (Office 365 US Government, Office 365 Germany and Office 365 operated by 21Vianet in China) are not currently supported.
  • The OneDrive and SharePoint app is compliant under Microsoft's publisher verification programme.

Note: When you create and share OneDrive or SharePoint files in Slack, you can search for them in your workspace, but they'll only be stored in OneDrive or SharePoint.


Connect OneDrive or SharePoint to Slack

Manage file previews

When you share a OneDrive or SharePoint file in Slack, you can choose if you'd like a preview to be displayed:

  • Add a preview
    A preview will be displayed when you share the file.
  • Don’t add a preview
    A preview will not be displayed when you share the file, but other file information will be visible.
  • Don’t add a preview or ask me again
    Previews will never be displayed when you share files, and you won’t see preview prompts.

If any members don’t have access to view or edit a file that you’ve shared with them, you’ll receive a message from the OneDrive and SharePoint app prompting you to adjust access to the file. To change access in the future, you can reshare the file and make adjustments:

  1. Next to a file that you’ve shared, open the drop-down menu.
  2. Choose who can view the file: Anyone in the conversation, Anyone in your organisation or Anyone with the link.
  3. If you like, you can also decide who can edit the file: Anyone in your organisation or Anyone in the conversation.
