Remarks

Deleted messages (POP3 protocol)

If a message was deleted by EmailDeleteMessage:

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

Therefore, if four messages are found on the server at the beginning of session, these messages are numbered from 1 to 4. If the message #1 is deleted:

EmailNbMessage used in the same session always returns 4.
Message 1 cannot be read by EmailReadMessage because the message does not exist anymore (only messages 2, 3 and 4 exist).

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

Deleted messages (Outlook messaging)

In the same email session, if a message was deleted by EmailDeleteMessage, EmailNbMessage returns the correct number of messages found in the incoming email folder.

Deleted messages (IMAP protocol)

If a message was deleted by EmailDeleteMessage, this message is actually deleted from the session:

during the next "expunge" command (clear the bin from a WebMail for example).
Versions 20 and later
when using EmailExpunge to force all the deleted emails to be destroyed.
New in version 20
when using EmailExpunge to force all the deleted emails to be destroyed.
when using EmailExpunge to force all the deleted emails to be destroyed.

New messages (POP3 protocol)

The POP3 protocol cannot be used to find out and manage the new messages received during the connection. To get the new messages, you must disconnect (EmailCloseSession) and reconnect (EmailStartSession).
