Didn't follow this whole thread but I see the "first email" problem and the Outlook model and I recognize this as we used this for 15+ years. Start Outlook once a day. Send your monitoring account the first email. Let it run all day.

Instead of using Outlook automation, and risking it breaking during every upgrade, and potentially being marked as a spammer, perhaps using a transactional email service might be an approach to consider.

This is definitely the way to go these days for bulk sending. Outlook, and specifically Outlook connected to hosted Exchange, is not designed to do bulk sends.

The problem happens on the *first* E-mail.

We are not doing bulk sends. Each of the E-mails is different. They are monthly invoices and possibly some other reports. There are less than 100 of them, and they are sent one at a time as they get completed.
