Seem there is TWO issues you encountered:

1. Outlook restricts user to send more than 10K Email in a 24-hour period
2. User mailbox restricts the number of Email address put in "To", "cc" and "Bcc" field to 500

For [1], may required a 3rd party such as SendGrid

For [2], please consider DL (Distribution List)

Create a (maybe dynamic) distribution list and send to it.
