I've discovered that Azure SQL no longer includes SQL Agent. For others that happen upon this post, my research found 2 alternative methods to send a scheduled email from Azure:
I may try this at a later date, but for now I will most likely have my Access app send the email on the first user shutdown after 4:30pm, and log it into a sent mail table so no further emails will be sent for that day, or send it upon the first login in the morning of the next day. It is not optimal, but it is my best choice for now.
Thanks to both of you!
If someone has a better idea, I'm all ears!
