Emailing from Access to Outlook using Query and Mailto:

[OBP]

Here is an example of the code you need from one of my databases

Dim subject As String, Body As String, EmailAddress As String, sql As String
Dim rs As Object, recount As Integer, count As Integer, swhere As String
On Error GoTo errorcatch
If Me.Extra = -1 Then ' you may not need this as it is a test to see if extra people are included
    sql = "SELECT emailExtraQuery.* " & _
    "FROM emailExtraQuery " & _
    "Where Xtra = -1" & _
    "And email = -1"
    Else
    If Me.Year <> "All" Then
        sql = "SELECT emailQuery.* " & _
        "FROM emailQuery " & _
        "Where RenewalYear = " & Me.Year & _
        "And email = -1"
    Else
        sql = "SELECT emailall.* " & _
        "FROM emailall " & _
        "Where email = -1"
    End If
End If
Set rs = CurrentDb.OpenRecordset(sql)
'MsgBox rs.RecordCount
If rs.RecordCount > 0 Then
rs.MoveLast
rs.MoveFirst
'MsgBox rs.RecordCount
recount = rs.RecordCount
For count = 1 To recount
    If Not IsNull(rs![Home e-mail]) Then EmailAddress = EmailAddress & rs![Home e-mail] & ";"
    If Not IsNull(rs![Work e-mail]) Then EmailAddress = EmailAddress & rs![Work e-mail] & ";"
rs.MoveNext
Next count
EmailAddress = Left(EmailAddress, Len(EmailAddress) - 1)
'MsgBox EmailAddress
DoCmd.SendObject , , , "if you want to send yourself a copy of the email put yor email address here", , EmailAddress, , , True
End If
rs.Close
Set rs = Nothing
Exit Sub
errorcatch:
MsgBox Err.Description

Note the true on the end of the docmd.sendobject shows you the email address before trying to send anything.
If you wish to compose the subject and body of the email prior to sending you can do so using a form to input them first as per the attached database.
