lifts the limits in the DL but even so, there may be limits on the SMTP
server.

I have a DL with 500 - 200 contacts in it that I have to create each time
I
want to send a delayed email message. Outlook is running in connect mode,
not
cached.
Not all contacts are receiving the email sent, internal contacts (within
the
company) seem to receive the email, but external clients do not.

Error Message: Operation Failed.
