This issue occurs due to incorrect MIME type configuration maintained in the system.

Path to check configuration:
Business Configuration Work Center → Overview → Search for "MIME" → Click on the hyperlink "Allowed MIME Types for Document Upload".

In this configuration:

• The .pdf file extension should be associated with the application/pdf MIME type.
• However, it is currently also associated with application/octet-stream.
• When multiple MIME types are configured for the same file extension, the system defaults to application/octet-stream, which results in the file being downloaded without a .pdf extension.

To resolve the issue:

• Remove the .pdf file extension from the application/octet-stream MIME type.
• This ensures the system uses the application/pdf MIME type for PDF files.
• After this correction, downloading PDF attachments from the email interaction preview will retain the proper .pdf extension and display correctly.
