EmailReadMessage (Function)

In french: EmailLitMessage

Reads an email received:

via the POP3 or IMAP protocol: the email is found in the in-box on the messaging server.
via the Lotus Notes or Outlook messaging software: the incoming email is found on the local computer in the in-box of Lotus Notes or Outlook.

This function does not modify the current position.

The variables of the email structure (or Email variable) are filled.

The Email.Out variable is set to True if no email is found.

Reminder: Before reading an email, it is necessary to open a session with EmailStartSession, EmailStartNotesSession or EmailStartOutlookSession.

The POP3 protocol can only be used to read emails.

Example

FOR I = 1 TO nbMSG
IF EmailReadMessage(NomUser, I) = True THEN
IF Email.Out <> True THEN

CL.MESSAGE_TXT = Email.Message
...

Remarks

Number of messages found in the mailbox (POP3 protocol)

The total number of received messages is returned by EmailNbMessage.

If a message was deleted by EmailDeleteMessage in the same email session:

EmailNbMessage returns the number of messages found on the email server before the deletion.
the numbers of the deleted messages are not re-assigned.

For example: During the connection, four messages are on found the server. These messages are numbered from 1 to 4. If message #1 is deleted:

EmailNbMessage returns 4.
EmailReadMessage cannot read message # 1: the message no longer exists. The Email.Out variable returns True. Only the messages 2, 3, and 4 exist.

The message numbers are re-assigned during the next connection.

Number of messages found in the mailbox (Outlook messaging)

The total number of received messages is returned by EmailNbMessage.

If a message was deleted by EmailDeleteMessage in the same email session, EmailNbMessage returns the actual number of messages in the inbox folder.

The attached files

When reading a message, the attached files can be copied to the local disk (or to the server disk) using EmailSaveAttachment.

Tip: We recommend that you save the messages and their attached files on the local disk (or on a server disk), then delete them from the email server. This operation is used to:

reduce the size of the mailbox on the server,
improve and speed up the communications on the POP3 servers: only the new messages will be read on the server.

Progress Bar

To track the progress of the email, use EmailProgressBar.

Outlook messaging

The WLanguage EmailReadxxx functions operate with the Outlook data file (.pst) only. The other data files are not supported.
