The update reflects a revised GA completion timeline for a new Teams feature allowing search for cloud files in the attach picker. The change primarily affects user workflows when sharing files and requires minimal admin oversight beyond awareness and optional comms. No policy, permission, or configuration changes are needed, so admin impact and effort remain low, while user impact is moderate due to visible UI enhancement. Urgency is moderate, mostly for awareness and documentation updates.

[Introduction]

[How this affects your organization:]

Who is affected:

  • Users who share and attach files in Microsoft Teams chats and channels using the quick sharing (Attach) experience.
  • Organizations that use cloud files available through Microsoft 365 (for example, OneDrive and SharePoint) in Teams.

What will happen:

  • Users will be able to search for cloud files directly in the attach file picker during the quick sharing experience.
  • The change reduces time spent browsing folders during file attachment.
  • Users will only see files they already have permission to access.
  • No changes are expected to existing file sharing permissions or policies.

[What you can do to prepare:]

  • Optional: Inform your helpdesk that users may notice a new search capability when attaching cloud files in Teams.
  • Optional: Update internal documentation or training materials related to sharing and attaching files in Teams.

[Compliance considerations:]

QuestionExplanation
Does the change alter how existing customer data is processed, stored, or accessed (e.g. documents, emails, chats, etc.), if so how and to what extent?This update provides a new in-product method to discover and access existing cloud files by enabling search within the Teams attach file picker; results are permission-trimmed so users only find files they can already access.
