Easiest way to find largest emails in Outlook app.

Hello everyone,
For work requirements I would need to extrapolate via Powershell or BAT the size of mail attachments for each of our users.
We use the Office suite as the program installed on the PC to which we apply the last year mail retention rule.
Looking online I find only total mailbox sizing or similar, I found however only this guide : https://support.microsoft.com/en-us/office/find-all-messages-with-attachments-b1395e66-804f-4d05-99ef-0fbd9618fecf which allows me to do what I am looking for but as anticipated before only on the last year of mail.
I certainly can't download every year so as not to fill up the PC disk and definitely an operation I can't do on more than 150 users.
Thank you all for the support!

    Actually I've just followed the second screen image (which I think should be separated from the first) and that has worked. So I've changed to "Focused", gone to "other" and then clicked on the double arrows at the end which allows you to order by size.

    I see no "Advanced View Settings",

    Or columns under "View Settings"

    under Help and search, columns doesn't show up.

    I have Microsoft Outlook Version 1.2024.327.300 (Production).

    Do I need a newer version?

    Thanks

    Dear Emir Guetari

    Good day! Thank you for posting in the Microsoft Community. We'll be happy to help!

    First of all, we apologize for the inconvenience and inconvenience caused to your work. Based on your description, you can easily find the largest emails by sorting your mailbox by size. Here's how:

    1. Open Outlook and go to the folder you want to search (e.g. Inbox, Sent Items, etc.).
    2. Click on the "View" tab in the ribbon.
    3. Click on "View Settings" and then "Columns".
    4. In the "Select available columns from" dropdown, choose "Size".
    5. Click "Add" and then "OK".
    6. Your mailbox will now display a "Size" column.
    7. Click on the "Size" column header to sort your mailbox by size, with the largest emails at the top.

    .

    You can check out the screenshot of my test above, so that all emails will show their size and will be automatically arranged in descending order.

    Thank you in advance for your understanding. Your patience and cooperation will be greatly appreciated. I hope for all the best!

    Sincerely
