'  body.

Dim j As Long

'  Show the total size of the email, including body and attachments:

'  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:
Dim numAttach As Long
numAttach = imap.GetMailNumAttach(email)
Debug.Print numAttach

Next

Debug.Print "--"

'  Disconnect from the IMAP server.
