Configuring POP3s/SMTPs access to Exchange 2010 (part 2 - POP3s)

POP3s:

• Setting up the X.509 certificate name: in EMC – Server Configuration/Client Access; highlight the server, click “POP3 and IMAP4” tab in the lower pane; highlight POP3/right click/Properties; on “Authentication” tab put popserver.yourdomain.com in the “X.509 certificate name” field

• Assigning the certificate to POP3:

Unlike the IIS, SMTP, the POP3 certificate assignment fails when you use the “normal” way (ie. Server Configuration/highlight the server/select the proper certificate in the lower pane/right click/”Assign Services to Certificate”), you have to run following command in the Powershell “Set-PopSettings –X509CertificateName popserver.yourdomain.com” (check PopSettings using the command “Get-Popsettings | fl”)

• Publish POP3 settings to outside:

Follow the article: http://exchangeserverpro.com/exchange-2010-publish-pop3-client-settings/ .   Basically, if you follow the article they have you do following:

•  Run command “Set-PopSettings –ExternalConnectionSettings {popserver.yourdomain.com:995:ssl}

• Check the setting by running “Get-Popsettings | fl”

• Do iisreset
