<Result> = <POP3 session>.OpenSession()

<Result>: Boolean

True if the session was started,
False otherwise. In case of error, the Variable ErrorOccurred is to True.
To get the details of the error, use ErrorInfo with the errMessage constant.

<POP3 session>: emailPOP3Session variable

Name of the emailPOP3Session variable corresponding to the email session to handle.

Remarks

POP3 and SMTP protocols

The different parameters passed to <emailPOP3Session variable>.StartSession are supplied by the Internet Service Provider or by the network administrator.

An Internet connection is required to manage the emails. Several cases may occur:

The user uses a direct connection to Internet (cable or ADSL): no specific operation is required.
The user uses a modem to connect to Internet: NetOpenRemoteAccess is used to establish the connection to Internet.

By default, if only the IP address of POP3 server is specified, this address will be used by the email server that uses SMTP. The IP address of SMTP protocol must be specified only if the POP3 account and the SMTP account do not use the same computer.

Authenticated SMTP

The SMTP authentication cannot be performed by <emailPOP3Session variable>.StartSession. To start a POP3 session and an authenticated SMTP session at the same time, you must use both EmailStartPOP3Session and EmailStartSMTPSession.

Timeout

The timeout can be set using EmailSetTimeOut.

Gmail: What to do if a connection to Gmail (SMTP, IMAP, POP3) fails with a certificate error?

Since August 2017, a new certificate was deployed by Google: Google Internet Authority G3. Unfortunately, the Windows API for checking certificates does not validate this certificate.

Therefore, starting a POP3, IMAP or SMTP session may fail with the error "The certificate string was not issued by a trusted authority".

To validate the certificate, all you have to do is modify the management mode of emails. The WLanguage EmailConfigure function allows you to change this mode and to no longer use the Windows API that locks this certificate. The following code must be added before starting the session via <emailPOP3Session variable>.StartSession:

// Activation de l'implémentation multi-plateforme
EmailConfigure(emailParameterMode, 1)

Remark: From version 23 Update 1, the call to EmailConfigure is not required anymore: WLanguage is automatically using the management mode of emails adapted to the session.
