configuring office 365 mail flow for evault smtp

Hello all, hoping someone can help me out here.  I'm trying to setup office 365 exchange to start journaling into evault.  I believe I have the server side of evault configured correctly but I am having a hard time figuring out the office 365 exchange configuration.  I tried to follow along in the guide here https://www.veritas.com/support/en_US/article.000116527 but haven't had any luck getting the o365 configured.  Can anyone who has done this configuration before hold my hand through the process?
