Help with Direct Send Issues and Voicemail Notifications

Asked by TechWhiz92
Hey folks! I'm having some trouble after disabling the Direct Send feature in our company's Exchange setup due to a lot of spam and fake voicemails coming through. While it seems like that solved the spam issue, older users are now not receiving emails for voicemails from our VOIP system like they used to. I've also noticed something odd: many users are getting redirected emails from Microsoft Teams about unread messages to our anti-spam inbox since I disabled Direct Send. I've read that some users are routing emails to their email filter instead of turning off Direct Sendโ€”how do you do that? I'd appreciate any guidance as I'm still learning in my junior IT role. Thanks a ton!

Are these spam emails appearing to come from your own domain? We're having a similar issue where it looks like users are forwarding spam to themselves, but they definitely didnโ€™t send those emails. It's like they bypass our spam filter completely and donโ€™t show up in the logs. We set up mail flow rules but are still struggling with the spam issue.

CyberKnight42: Do you have the Proofpoint connector set to restrict direct sending to your Microsoft MX record? I've found this really helps in controlling spam.
