Automatic Updates is enabled on our Server 2012 / Exchange 2013 box. Updates were installed on the 17th and internal mail and safe senders started going in to users junk mail in Outlook. If I disable the firewall and have users close and reopen outlook mail no longer goes to junk. I dont know what the proper firewall settings are to correct this. The firewall setting say inbound connections that do not match a rule are blocked. I would be happy to post a screen shot of allowed connection in Windows firewall if it will help.

One more thing to note is I can not ping the mail servers external ip or FQDN. It simply times out.

Is this for all mail clients or just certain ones? Are you users using cached mode for Outlook? What updates were installed on the 17th?

Do you have a split brain DNS setup? domain.internal and domain.external? If you do do you have your domain.external setup as a zone in DNS?

Have you checked the logs on the Exchange server to see if anything is showing warnings or errors?

All internal clients. Yes we are using cached exchange mode. Split DNS is not set up. Several updates were installed. I will get a list.

Hi, We are still having this issue. It seems now only emails to our internal distribution groups are being flagged as spam.

We use GFI mail essentials to filter spam. GFI support is telling us our internal mail is being sent from Outside the Organization.

How do I verify and correct this? I can not find the Best Practices Analyzer tool for Exchange 2013.

Are there any other tools to verify my server is correctly configured??
