While saving an email, attachment filename is getting truncated at '.' (dot)

Hi Experts,

I need your help here.

When I am saving an email the name of attachments in the email are getting truncated where there is a dot present in the attachment name.

For example is the attachment name is abcd.xyz then after saving it in local drive attachment name will become abcd

I think may be some sap note will be required here.

Thanks & Regards,

Kapil Kumar
