Using New Outlook on Windows for professional communication and productivity
Hello Mazhar Hussain,
Thank you for explaining the issue.
Please refer to the AI-generated answer in this thread and try the suggested search and filtering options. In Outlook, an attachment remains linked to the specific message where it was originally added. It is not automatically included in later replies within the same conversation, so you may need to expand the thread and open the original message that contains the attachment. For your reference: Find all messages with attachments in Outlook | Microsoft Support
If you still cannot locate the file, could you please check the same conversation in Outlook on the web and confirm whether the attachment is visible there?
Please also confirm whether this happens only with this specific email thread or with every conversation containing attachments. It would also be helpful to check whether the original message has been moved to another folder, such as Archive, Sent Items, Deleted Items, or another custom folder.
If the attachment is available in Outlook on the web but not in New Outlook for Windows, the issue would be specific to the desktop application or its conversation view. If it is missing from both versions, the original message may have been moved, deleted, or stored in another folder.
Please update me with the results. If possible, share a screenshot showing the expanded conversation after hiding all email addresses and other sensitive information.
Kind regards,
