How to display SMTP info on Outlook Web App

Share this:

In the users’ options there is a place that provides information to the end-user how to connect using legacy protocols, such as SMTP, POP and IMAP.


If you are not familiar with those options, you can log on Outlook Web App, and then click on the username and then Options, in the main page under account click on Settings for POP or IMAP access… and a new window will be displayed with all information required to connect on those services. That information must be configured on the server side first, before being displayed to the end-users and on this Tutorial we will focus on the SMTP portion of that window.


By default all Receive Connectors have the parameter AdvertiseClientSettings defined as False, and that is the property that define what is going to be showed up on that page.


The first step is to configure a FQDN on the Receive Connector, Exchange Server 2013/2016 already have a built-in connector which is configured to accept authentication from the clients. The name is Client Frontend <ServerName> and it is configured to listen on port 587. In our Tutorial, we are going to configure on that specific receive connector and save the configuration.


The second step is to configure the AdvertiseClientSettings parameter at the Receive Connector level, and we can do that using the following cmdlet, and the results can be seen on the image below.

Set-ReceiveConnector <ServerName\ConnectorName> –AdvertiseClientSettings $True


After performing those changes, the end-user can log on Outlook Web App and access the same page, and at this time the SMTP information will be displayed.


In some cases, you may want to restart the IIS using iisreset to refresh the settings.
