If you have users who use POP3 or IMAP4 to connect to their Microsoft Exchange Server 2013 mailboxes, they need to know the correct server settings to connect. After a default Exchange 2013 installation, your users can’t look up their own incoming POP3 or IMAP4 server settings or outgoing SMTP server settings. However, you can configure Exchange so that your users can look up their own settings using Microsoft Outlook Web App.

After you perform these procedures, your users can look up their server settings in Outlook Web App as follows:

  1. In Outlook Web App, click Settings > Options.

  2. In Options, click Account > My account > Settings for POP or IMAP access.

For additional information related to POP3 and IMAP4, see POP3 and IMAP4.

What do you want to do?

Use the Shell to allow POP3 and IMAP4 users to view their incoming POP3 and IMAP4 settings in Outlook Web App

You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "POP3 settings" and "IMAP4 settings" entries in the Clients and Mobile Devices Permissions topic.

This example allows external POP3 server settings to be viewed by end users.

Copy Code 
Set-PopSettings -ExternalConnectionSettings {Dublin01.Contoso.com:995:SSL}

For detailed syntax and parameter information, see Set-PopSettings.

This example allows external IMAP4 server settings to be viewed by end users.

Copy Code 
Set-ImapSettings -ExternalConnectionSettings {Dublin01.Contoso.com:993:SSL}

For detailed syntax and parameter information, see Set-ImapSettings.

To apply these changes, you must restart IIS. You don’t need to restart the POP3 services. To restart IIS, from a command prompt, enter the following:

Copy Code 
iisreset
