FortiAuthenticator with office 365 as SMTP server

[Anonymous5]

Hello,

I use FortiAuthenticator as my OTP server for SSL-VPN, it send email to the user with token for 2FA.

We would like to set office365 as the SMTP server but we got errors:

smtp starttls: verify peer certificate: unable to get local issuer certificate

Can someone please guide me how I should configure on the FortiAuthenticator and on office365 side?

Should I configure it like fortiemail?
