Hi.
- On firewall level we have closed outbound connection from VBR to WAN.
- We have created exceptions for typical SMTP ports: 587, 25 for outbound traffic.
- We have created exceptions HTTPS outbound rule only for specific domains: *.microsoft, *.office365.com, *.veeam.com
- SMTP server is set as: smtp.office365.com
- Test messages is sucessfully.
But when we confirm e-mail settings a pop for checking certificate is shown.
I'm guessing that we must create allow outbound rule also to some CRL's because above check doesn't pass?
Any ideas.
Thank you.

Re: VBR e-mail settings to O365 (check certificate)
Hello Bostjan
Which version of Veeam Backup & Replication is currently running on your system?
There were cases in the initial v12 builds where users encountered certificate errors while testing SMTP. This should be solved by now (most recent patch of v12, v12.1).
Another question If I may:
Why are you not using the Microsoft 365 OAuth 2.0 to send the mails?
Best,
Fabian
