MC1253753 - Whiteboards created in Teams channels will now be stored in SharePoint

Introduction

To improve reliability, compliance, and collaboration, we’re updating where Microsoft Whiteboard files created from a Teams Channel tab are stored. Previously, these whiteboards were saved in the OneDrive of the user who created them, which could lead to access issues due to sharing settings, Information Barriers, or Conditional Access policies.

With this update, whiteboards created from Teams Channels will be stored in the associated SharePoint site for the channel, aligning Whiteboard with the storage behavior of other Microsoft 365 apps and ensuring consistent access for all channel members.

When this will happen:

We will begin rolling out this change in late September 2026.

How this affects your organization:

• Who is affected:
  • All Microsoft Teams users who create or collaborate on Whiteboards using the Teams Channel tab app
• What will happen:
  • Whiteboards created from a Teams Channel tab will be stored in the channel’s SharePoint site.
  • All channel members will have consistent access based on channel permissions.
  • Existing Microsoft 365 compliance and security policies continue to apply.
  • Whiteboards will be discoverable from the Whiteboard board picker.
  • The change is enabled by default.

What you can do to prepare:

No action is required from administrators.

Recommended optional steps:

• Review internal documentation or helpdesk guidance that references Whiteboard storage locations.
• Inform support teams that Whiteboards created in Teams Channels are now SharePoint-based for troubleshooting and access requests.
