Expand File Attachment View in MS Outlook

Question

Please include the expansion of file attachment names in the new Outlook. The limit seems to have been changed to a minimum of attachment views. The option to expand is very small. Please enlarge this to where the default view is at least 8 files and default the option to expand to a much larger (in bold visible font) whereas please can see the option to expand clearly. It is causing confusion with recipients viewing the email as missing file attachments. Please expand the file attachment view and/or make the option to expand attachments much more visible to the user and the recipient. Thank you.

Dear Jennifer,

Thank you for letting me know, and my apologies for the inconvenience. From my research, the message you received suggests that the account you are signed in with is not one of the account types currently permitted to use the Microsoft Feedback Portal. The portal currently supports:

• Microsoft personal accounts (MSA), such as Outlook.com, Hotmail.com, or Live.com.
• Microsoft Entra ID (Azure AD) accounts in supported commercial cloud tenants.

If you are using a government, education, nonprofit, sovereign cloud, or another unsupported tenant type, you may see this blocked message even though you are successfully signed in.

Things you can try:

1. Sign out of all Microsoft accounts.
2. Open an InPrivate / Incognito browser window (Ctrl + Shift + N).
3. Sign in with either a personal Microsoft account, or a different Microsoft 365 commercial work account if you have one available.
4. Revisit the feedback portal and try voting again.

If the Feedback Portal continues to block access, you can submit your feedback directly from within New Outlook instead:

Help > Feedback > Make a suggestion

This sends your feedback directly to the Outlook product team and avoids the portal access issue entirely. It is a perfectly valid route, and your input still reaches the same team.

Thank you for your patience and understanding. Please let me know if you need anything else.

Answer 2

Dear Jennifer,

Good day, and thank you for reaching out to the Q&A Forum. I understand your concern about the limited attachment view in New Outlook, and I can see how the small Show all attachments control could easily cause recipients to think files are missing from an email. That is a genuinely valid usability concern. From my research, the number of visible attachments and the placement and visibility of the Show all attachments control are currently controlled entirely by the Outlook user interface. Unfortunately, there is no user setting or admin policy that allows you to:

• Increase the default number of visible attachments.
• Force attachments to be expanded by default.
• Make the expand control larger or more prominent.

One practical workaround is to compress multiple attachments into a single ZIP file before sending. This way, recipients see one clear attachment rather than a truncated list, which removes the risk of them missing files.

If this is a feature you would like to see, I suggest keeping an eye on the Microsoft Outlook(new) blog or the Microsoft 365 Roadmap | Microsoft 365 for any updates on this feature. In the meantime, I apologize for the inconvenience this may cause. I also strongly recommend that you share your detailed experience and feedback directly with the Microsoft product team through their official channels. This is the most effective way to make your voice heard and influence future feature improvements and adjustments. 

You can visit the Outlook (new) · Community to submit a new idea or vote on existing one here: Always Show All Attachments List, Critical Usability and Business Risk Issue. I would strongly encourage you to upvote this idea and add your own comments describing how it affects your recipients. The product team is in charge of this site, and they constantly check customer reviews and feedback. The higher the number of votes, the more attention the team will pay to it. Many features are developed and improved based on customer feedback. As a moderator, I will also pass along your feedback to the appropriate team for further consideration. While we don't directly influence product design, user feedback is actively reviewed and helps prioritize future development. If you’re unable to submit feedback yourself, please feel free to reach out to me, and I’ll be happy to submit it on your behalf. 

Thank you again for raising this, and I really appreciate your patience as New Outlook continues to evolve. Please feel free to reach out if you need anything else.
