This is everything I declare when using Notes code. It works well for my purpose, which pastes excel data from a userform into a memo and sends it off.

[vba]
Dim Maildb As Object 'The mail database
Dim UserName As String 'The current users notes name
Dim MailDbName As String 'The current users notes mail database name
Dim maildoc As Object 'The mail document itself
Dim Session As Object 'The notes session
Dim Subject As String 'The subject string
Dim ReturnReceipt As String 'The ReturnReceipt string
Dim Recipient As String 'The Recipient string (or you could use the list)
Dim ccPerson As String
Dim Recip(10) As Variant 'The Recipient list
Dim BodyText As String 'The body text
Dim SaveIt As Boolean 'Save to sent mail
Dim WasOpen As Integer 'Checking to see if the Mail DB was already
Dim ClipBoard As DataObject
[/vba]

Just makes sure the notes references are checked.
