How to send bulk email with Office365

These are the Office365 MaxBulk Mailer settings:

SMTP server access
	SMTP Host	smtp.office365.com:587
	Connections	5
	Security	TLS v1 Exp
Authentication
	Authentication	ESMTP | Login
	Account ID	<your_maxbulkmailer_mailbox_id> (Create an App password for MaxBulk Mailer)
	Password	<your_maxbulkmailer_password> (the password of the mailbox you have created for MaxBulk Mailer)
Delivery
	Delivery	Singly
	Group mails	25
	Interval	00:03:45
Sender information
	From	<your_sender_address>
	Name	<your_display_name_here>

Note that Office365 has several delivery limits: 10'000 messages with up to 500 recipients per message in bulk mode. More information here.

Always double check email addresses of recipients (with eMail Verifier) before hitting the Send button. That’s because your account will get disabled if the email message contains a large number of non-existent or broken addresses (<25 ?) that bounce back on failed delivery.

It is recommended to create an App password for MaxBulk Mailer. Use that App password as your Office365 credentials in MaxBulk Mailer.
