Hi @Daniel Esteban Montoya Muñoz ,
There is no built-in feature in Outlook desktop client that can generate a report of email attachments.
Based on my research, you can use some methods to find and manage your attachments:
- You can use sign in your account via Outlook on the Web and select the email in which you want to know the total number of attachments. There, you'll see the counted number shown as below.
- Besides, you may check if there is a Macro or VBA Code which might help:
Here are some links for your reference:

Microsoft does not guarantee the accuracy of this information.) For development vba code issues, it is recommended that you post with the ““office-development”” tag to get more professional help.
