recipient email address is invalid, but resolved property is true

[Mark VII]

Greetings --

I'm working on some email automation via VBA. (For a variety of reasons, I
can't use the system address book, and keep the email addresses in an Access
table. Long story.) I want to be able to protect against a fat-fingered
address in the table.

What I have so far creates the MailItem, adds a recipient, then uses the
Resolve method to make sure the email address exists in our system. (We have
Exchange servers.)

What is happening is the resolved property is returning True, even if the
address is invalid.

Here's a code extract:

Dim appOutlook As Outlook.Application
Dim nsNameSpace As Outlook.Namespace
Dim miMailItem As Outlook.MailItem
Dim rcpRecipient As Outlook.Recipient

Set appOutlook = CreateObject("Outlook.application")
Set nsNameSpace = appOutlook.GetNamespace("MAPI")
Set miMailItem = appOutlook.CreateItem(olMailItem)
miMailItem.Subject = "some text"
Set rcpRecipient = miMailItem.Recipients.Add("(e-mail address removed)")
If rcpRecipient.Resolved = True Then
'* OK, continue
Else
'* issue error message and abort
End If

The Resolved property always returns True, I can't trap for an invalid email
address. Should I be doing something differently to detect an invalid
address?

Thanks,
Mark

How could Outlook possibly know if that was an invalid address?

If the format of the email address is correct it will resolve. That doesn't
mean that it's an actual email address that you can send to.

I can resolve (e-mail address removed) but that doesn't mean that address actually
exists anywhere.

An SMTP address in the format (e-mail address removed) is always a valid email
address to Outlook and will always resolve regardless of whether it exists
in any of the user's address lists.

Sue and Ken --

Thanks for clarifying. I wasn't sure if an email address in internet format
was actually validated or not.
