Hi @Gautam Gattu 

OOTB the email attachments remain at the inbound email records, which makes sense in most of the cases.

If you want them on target record you have to implement that behaviour by yourself.

A simple and fast approach is to use a flow. On https://docs.servicenow.com/bundle/paris-servicenow-platform/page/administer/flow-designer/reference... you can find an example.

Kind regards
Maik
