Disable all email notifications

Question

I am working on a migration from 2010 to 2013 and have setup a development farm. I need a way to disable all outgoing emails or have all emails go to me. I have searched but can not find anything on disable emails. Does anyone know how I can do this?

Answer 1

I know, one method which i used in my test farm. Basically i remove the all settings from the Outgoing email setttings from Web App.

For Single Web App:

• Central Administration > Application Management > Manage Web Applications.
• On this page click on the web application name then from ribbon Select the Outgoing email settings( if click drop down of General settings).
• Now remove the Outbounf SMTP server name and other settings.

this will disable outgoing emails for the web application.

For the complete farm, you can remove the same setting

• Central admin > System Settings > Configure outgoing e-mail settings.
• On this page remove all the values.

Answer 2

I had a scenario where I had to turn of mail for certain web applications but I did not want to disable outgoing mail totaly. It is a testfarm.

I used this script to set SMTP server for each Web Application with url that contains sp2010. Where "turnedOff" is a false smtpadress to make sure the webapplications does not use the default SMTP set for the farm.

$wa = Get-SPWebApplication | where {$_.url -like "*sp2010*"}
foreach($wp in $wa){
$wp | Set-SPWebApplication -SMTPServer turnedOff
$wp.update()
}

or for simply 1 web application:

Set-SPWebApplication -Identity "http://someURL" -SMTPServer TurnedOff
