MC1120868 - Outlook for iOS and Android | Browse conversation files

Introduction:

We're introducing a new feature in Outlook that helps users quickly find and access all files shared within a conversation thread. Instead of scrolling through individual messages to locate attachments, users will see a Browse Files button at the top of the conversation view that opens a consolidated list of all shared files. This feature is supported exclusively on Outlook for iOS and Android.

When this will happen:

General Availability (Worldwide, DoD, GCC, GCCH): Rollout began in early July 2025 and completed in late July 2025.

How this affects your organization:

Once this feature is available, users who have set their Mail view to “Newest on Top” will see a new Browse Files button at the top of conversation threads. Selecting this button will display all classic attachments shared in that conversation, improving discoverability and productivity.

• The Browse Files button is always visible when the “Newest on Top” setting is enabled.
• This feature is exclusive to mobile clients—only available in Outlook for iOS and Outlook for Android. It is not supported in Outlook on the web or desktop.
• Users can only reference local files (classic attachments); links to files in OneDrive or SharePoint are not supported.
• This feature is on by default and requires no admin configuration.

• The visibility condition tied to the “Newest on Top” setting.
• The limitation to classic attachments (no cloud file links).
