Recommendations for Office365
1. If you don't have one, please create a service email account, like "support@your-domain.com". All of the Wizer emails will come from this email, so we don't recommend using personal ones.
2. Turn on 2fa for this account.
3. Create the "app password" that will be used specifically for Wizer custom SMTP. Please, see instructions here:

4. Finally, go to the Wizer White Label settings page and provide your email and password. For the host, use smtp.office365.com and for port - 587
5. Save and Verify. You should receive a success message.
6. You are done! If you will ever want to switch back to the Wizer email server, you will be able to do that by clicking "Reset Default".
