Failure to deliver emails to the outside (gmail, external domain, etc)

Hello Team,
Yesterday at 7:30 pm I have an Exchange server I am in charge of that could no longer send emails to the outside and therefore no longer receive any. The internal emails were working. around midnight, the external emails started working again. i don't understand what happened. Which logs can i look at to understand this malfunction? Every avenue of investigation and understanding is welcome.
Version : Exchange server 2010 SP3
Windows Server 2008R2 SP1

Hi timgreen7077,
all right. I'll check the event logs on the mail server. Thank you I'll let you know if I find anything.... or not ;-)

I looked at the application event logs but unfortunately I did not find anything as anomalies concerning the transport of emails. I will consider that it was an external problem to my Exchange servers.
Thank you for your help.
