Exchange on-prem and Global Catalog Servers
Hi everyone, We have an Exchange 2016 server on windows server 2016. And there are 3 DC and GC server that Exchange uses. I listed them withGet-ExchangeServer -Identity “ServerName” -status | fl command. One of the GC server is Server 2012 and the others are server 2016. I noticed repeated error messages on Application logs event viewer about the 2012 server. The message is below: What must we do?

On Premise Exchange 2019- Issue sending to external addresses
This is my first on-premise Exchange setup since back in 2008SBS, so please forgive my ignorance...lots has changed. My 2019 Exchange setup is being created for around five users in a small office, so we'd like to keep things simple. No smart connectors. Simple direct connection to ISP via firewall. Not worried about receiving mail from external sources for the time being. External Domain name: example.com hosted on a standard webhost which hosts our website Internal/local Domain Name: whatever.example.com I'd like the mail to show as coming from example.com. My internal e-mail all works fine. However, when I send to external addresses, the e-mail is blocked as Junk by the external SMTP server (my ISP's server) because the outgoing mail comes from my internal server/domain (whatever.example.com) - which of course doesn't exist externally, so it is marked as SPAM by the ISP. Yet, when I run the testconnectivity (Outbound SMTP) tool, it passes with a warning about an SPF record (which, of course, doesn't exist for whatever.example.com). I'm sure I'm missing something simple, but my searches have come up empty so far. Any direction would be appreciated. In the old SBS editions, a person could simply enter the SMTP FQDN of the ISP and external SMTP worked...that's sort of what I'm hoping to emulate. Thanks!
SMTP relay - Client host rejected: AP0002
Hello everyone, We have to send emails to a Bouyges address (a french telecom company) and I got this back: Sorry, no SMTP connection got far enough; most progress: RCPT TO response; remote host said: 554 5.7.1 <...dsl.sta.abo.bbox.fr>: Client host rejected: AP0002 Please use your ISP mailserver. (#5.5.0) I searched on Google to find a way to send the emails and what I understand is that I have to configure the SMTP relay of Bouyges. What I found are only configurations for postfix and I don't know how to configure it on an Exchange On-premise server, do you have any info? The SMTP server of Bouyges issmtp.bbox.fr What I don't know if it's possible to do is to use this relay only for the bbox mails address. Thanks for any help!
DMARC reporting for Exchange on-premise
I need advise on generating human-readable DMARC reports without the use of any external reporting services provided by many companies out there. I was hoping someone has any idea of a tool that can be installed and used on-premise. It would be nice to have if the tool is also able to present recommendations or remediation tasks. Thank you.
