How to customize the from address in send Email activity using Outlook

We are trying to send a mail using ‘Send Outlook mail’ Activity ,we need to customise the from address.How can we do it?Please reply ASAP

We are getting ‘To’ Mail as ‘From’ address.
Example : To email:
getting mail From

Thanks in advance!!

If that ‘from address’ is configured in your system outlook, then you can directly mention that id in from address. And if that ‘To mail’ value is changing frequently and not configured then I think you have to use SMTP mail activity. But for that you should be knowing configuration of that mail id.
