@SIM_JUN_HUI_BERTRAM_CSOD,

you’re directly providing List of Mail to attachment(IO_mail)…

Can you follow screenshot as below?

mail variable in for each must be type of System.Net.Mail.MailMessage

i followed ur method but it is now showing an error object reference not set to an instance of an object

@SIM_JUN_HUI_BERTRAM_CSOD,

I guess that IO_mail variable coming as empty, please run in debug mode or print number of mail like IO_mail.count in log message.

nvm i found out why it was causing this problem due to too many emails containing the same subject actually causing this error.

@SIM_JUN_HUI_BERTRAM_CSOD,

There is a property Top to read number of email like 5, 10 etc…
you can also apply condition for specific attachment to be saved.

Thanks,
