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:]

Question	Explanation
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.
