MC746332Microsoft Teams: New Admin control for setting default storage app for file uploads

Updated May 24, 2024: We have updated the rollout timeline below. Thank you for your patience.

We continue to enhance the Microsoft Teams platform with deeply integrated experiences and greater admin controls to enable a seamless collaborative experience for content stored on third-party cloud platforms. Teams admins will soon be able to change the default storage app for file uploads in Teams from Microsoft OneDrive and SharePoint Online to a third-party provider of the admin's choice. This setting will only apply when local files are uploaded using drag-and-drop in Teams chat and channel conversations.

This setting does not apply to Teams mobile and these user actions on Teams Desktop:

• Pasted images or media files in Teams chat and channel conversations
• Files uploaded using the default attach file icon (paper clip)

This message is associated with Microsoft 365 Roadmap ID 376219.

When this will happen:

Targeted Release: We will begin rolling out early April 2024 and expect to complete by mid-April 2024.

General Availability (Worldwide GCC, GCC High, and DoD): We will begin rolling out mid-April and expect to complete by late May 2024 (previously early May).

How this will affect your organization:

If your organization is not using a third-party storage provider on Teams, this feature may not be relevant.

If your organization is using a third-party storage provider on Teams, admins can use a PowerShell command to set the default content app for local files uploaded using drag-and-drop in Teams chat and channel conversations. We will update this post before the rollout date to provide documentation on using the PowerShell command.

What you need to do to prepare:

Third-party developers will need to update their apps to support the new admin settings. Admins should refer to third-party storage provider documentation or reach out to third-party storage providers for more information on support for the new settings.

This rollout will happen automatically by the specified date with no admin action required. You may want to update any relevant documentation as appropriate.
