Runtime error if contact in Outlook doesn't exist - vba

Question

When I complete a piece of work I email it to certain people. It depends on the work who gets it.
If any person in the list leaves, changes job or has an email change the code will bug out saying
Run Time error -2147467259(80004005), Outlook Does Not Recognise One Or More Names
If I manually copy the email addresses in the list and pop them into Outlook and send I'll get an email back saying the user doesn't exist or has been changed.
I have tried On Error Resume Next and On Error Goto. I have added MS Outlook 14.0 Object Libary, SharePoint Social Provider, Social Provider Extensibility and Outlook View control from the references.
The code bugs out on the .send
Sub EMailer()
Application.ScreenUpdating = False
strfilepath = "\\DFZ70069\Data\199711009\workgroup\Res Plan Team\Performance Management\Specialised Reporting\Debit & Credit Reporting\Masters\Sent Reports\"
strArea = "Recipients" '..........................................................................................
'Get list of recipients for email
For Each cell In Worksheets("EMails").Range(sRange)
If cell.Value = "" Then GoTo Continue
strmaillist = strmaillist & cell.Value + ";"
Continue:
Next
[B1].Value = strmaillist
If bMyEmail = True Then
strmaillist = strmaillist & MyEmailAddress
End If

You can try to check the validity of the recipient before sending, by using the .Resolve method of the Recipient object. Only valid recipients can be kept in the Recipient list of the mail item.
You might try this:
Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)
With OutMail
.Subject = sReportName & " Report " & strDate
.HTMLBody = "Set to HTML" & vbLf & vbLf & ""
.Body = strbody
.Attachments.Add (strfilepath & sTemplateName)
For Each cell In Worksheets("EMails").Range(sRange)
If cell.Value <> "" Then
set r = .Recipients.Add(cell.value)
If Not r.Resolve then r.Delete '<~~ Removes invalid recipients
End If
Next
.send
End With
