(VBScript) Fetch Oldest/Newest IMAP Email

Emails may be downloaded by sequence number. Assuming the selected mailbox is not empty, the oldest email is at sequence number 1, and the newest email is at sequence number N. The FetchSingle method may be used to download by sequence number.

Note: This example requires Chilkat v11.0.0 or greater.
