I decided to switch over from a Outlook to an SMTP relay from https://www.mailjet.com and that worked well for me. I kept LOGIN, inputted the API keys into the username and password fields, and everything worked out. It has been working well.
The reason I switched over from Outlook is because, for some reason, after sending one email correctly… it wouldn’t work again for hours on end. I decided to just go search for some free SMTP providers, and came across MailJet. Since then, the emails get sent correctly.
Thank you for the support. Have a great day!
