Fetch Single Email by UID or Sequence Number

Assuming the UID is known, download a single email by UID from an IMAP mail server. VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

set imap = CreateObject("Chilkat.Imap")

' Use TLS
imap.Ssl = 1
imap.Port = 993

If (success = 0) Then
    outFile.WriteLine(imap.LastErrorText)

End If

' Login
success = imap.Login("***","***")
If (success = 0) Then
    outFile.WriteLine(imap.LastErrorText)
    WScript.Quit

' Select an IMAP mailbox

' Display the From and Subject
outFile.WriteLine(email.FromAddress)
outFile.WriteLine(email.Subject)

' Display the Body property, which is the default body.
' If an email has an HTML body, the Body property contains

outFile.WriteLine(email.Size)

' When a full email is downloaded, we would use the
' email.NumAttachments property in conjunction with the
' email.GetMailAttach* methods.
' However, when an email object contains only the header,
' we need to access the attachment info differently:

' Disconnect from the IMAP server.
success = imap.Disconnect()

outFile.Close
