Send Email Fails

[Marutha_K]

I am trying to use "Sen Email" activity for sending email with attachment but it's failing with the below error message. Any help on this appreciated:

1. I have enabled emails to be sent from the server which am using - Firewall is open 

2. Below is the list of settings used in Send Email activity:

What am missing in the settings? Any help is greatly appreciated. Thank you!

Hi @VJR  I am using Office 365 - email for sending email.

Hi @Marutha_K ,

Plz change smtp address smtp.office365.com and port will be 25 or 587.

All the configurations are correct in the Send Email activity but the machine/server from which this flow is running is not allowed to send email. Hence the server IP is whitelisted and allowed to communicate with relay server and then everything perfectly.
