CDO Message: The server response was not available

Hello,

The code below used to work flawlessly when sending email reminders. However, I recently added 2-step verification on my gmail account for
extra security and now I am getting the error below. Is their a work around?

Run-time error '-2147220975 (80040211)':

The message could not be sent to the SMTP server. The transport
error code was 0x80040217. The server response was not available

    Set iConf = CreateObject("CDO.Configuration")

Hi Leith,

Sorry for my delay...I have been swamped with work.

I have replaced "25" with "465" in this line of code:

.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25

However, I am still getting the same error.

Thanks.

Thanks, Leith. I will look into it and report back. But you don't think it is being caused by the 2-step verification feature from Google, right?
