If you're using Office365 with double authentication, please follow this 4 steps tutorial to set up your SMTP. Mailwarm generates interactions between your email account and its own accounts. In order to make it work, you need to set-up your SMTP (simple mail transfer protocol).

Step 1 : Reach the App passwords page

Sign in to your Office365 account and go to Additional security verification page, and then select App passwords. You'll only see this option if your admin has set up multi-factor authentication for your organization. If you don't see this option, please contact your Office 365 admin and tell them to turn on multi-factor authentication.

Step 2 : Create a new App Password

An app password is a security layer that Office365 generates, so you can use apps like Mailwarm without your main password. Select Create, type the name of the app that requires the app password, Mailwarm in our case, and then select Next.

Step 3 : Copy the password

Copy the password from the Your app password page. You'll need it to configure your SMTP on Mailwarm. Then select Close.

Step 4 : SMTP settings on Mailwarm

Go on Mailwarm, and add a new email account. Then fill in the SMTP form as following :‍

Email address : your email address

Reply-to email : your email address

SMTP Host : smtp.office365.com

SMTP Port : 587

SMTP Protocol : TLS

SMTP Username : your email address

SMTP Password : the App Password you've just generated

Hit the Test & Save button, you'll receive a confirmation email if this properly worked.
