Though it’s quite simple to configure emails on SP and PS, there are a couple of reasons I wanted to post about it.
First, we’ll see where we need to go and configure SMTP settings for emails.
Central Administration -> System Settings -> Configure outgoing e-mail settings [Under E-Mail and Text Messages(SMS)]
Web Application Level:
Central Administration -> Application Management -> Manage web applications [Under Web Applications]
Select web application and click General Settings [Under Manage] and then select Outgoing E-email settings.
Project Server Instance Level:
Central Administration -> Application Management -> Manage service applications [Under Service Applications]-> Project Server Service Application
Select the PS instance and click Manage and then select Alerts and Reminders under Operational Policies.
