Hello!

few questions if someone can help please:

1. The email account used in SMTP setup, does it need to be a shared mailbox?

2. Do the users need to have full access or send as permissions to be able to send emails from BC?

3. the email account specified in smtp setup - does it have to be setup as BC user with BC license assigned?

any other helpful info very much appreciated!!

Have a great Friday/weekend!!

I think this is because of MFA (Multi Factor Authentication) you need create an app password and use that. Please see below link for more infor

Hello Suresh!

thanks so much for your message!

This helped me so much!! It wasn't the MFA but I have learned for future reference where to check if it is enabled..

while digging around based on the article I found that the user's pw was expired.. once I did pw reset it worked!

thanks again!!
