Re: [mailop] Office 365 Assistance
If, as you say, they are Office365 customers, they could always open a ticket with Customer Support …. What are the sending IPs?

We’ve been working with The Home Depot on their Retool Your School Program (https://retoolyourschool.com/) for more than ten years now. Over the past year and especially the last few months, we are having a hard time getting their emails to the intended recipients with a lot of their messages going to junk. All the messages are going to HBCU’s (Historically Black College and Universities) and a lot of them are using Microsoft Office 365. We’ve begun to ask the colleges to mark their IP, domain, and email address as safe senders but it’s hard to reach everyone personally. The messages are not bouncing back, just ending up in Junk for a large majority of subscribers. This is a 100% opt-in program, and the list size is under 700 subscribers. They send out once to twice a week from December through May. All the colleges are competing for more than $500,000 in campus improvement prizes and many schools can’t participate because they aren’t receiving the emails. They have a dedicated IP address and custom DNS. It’s setup with SPF, DK, DKIM, DMARC, SNDS, JMRP, and a “List Unsubscribe” in the header. I’ve filled out the forms for Office 365 support and the IP isn’t blocked. I also filled out the Microsoft support form and the IP is also not blocked there or any indication through SNDS that there are any issues. If anyone on list may be able to help, the program would be greatly appreciative. Thanks, Michael Michael E.

Re: [mailop] Office 365 Assistance
Hi Michael, I'm seeing this issue quite often lately and in the majority of the cases the problem is when M365 email hosted companies are using an extra layer of email hygiene (Mimecast, IronPort, etc) before their Exchange Online Gateway because some of them are still using the Exchange DMARC checks and doing the checks against their own hygiene layer instead of the original sender. You would be able to confirm this if you check the routing in the email headers of those messages placed in the Junk folder. Hope this helps, Toni On Wed, Feb 2, 2022 at 5:58 AM Michael E.
