Microsoft 365 Issues - Restricted Entities List

HMJB — Wed, 28 Aug 2024 21:18:51 GMT

Hello! I'm reaching out to any Hubspot support personel or fellow Microsoft 365 customers that can offer any advice. We use Microsoft 365 Exchange for email and Outlook with the Hubspot add-in. This add-in adds a hubspot email address in the Bcc field for every outbound email. Microsoft hates this. When enabled, (and this is reproducable), if the user sends over 100 emails within 24 hours, the user will end up in the Restricted Entities list: Microsoft Security Console > Email & Collaboration > Review > Restricted Entities.

In my experience it is impossible to communicate sufficiently with Microsoft support to reach an acceptable solution. The only option we have found is to turn off the auto-bcc.

Surely thousands of other Hubspot/Microsoft customers are dealing with this issue. Are there any known solutions or workarounds? Thanks!

Hey, @HMJB 👋 I think your approach of working with MS Support is the best path forward. Our community is a peer-to-peer support community, and our support team cannot assist in this space. If you have a subscription to HubSpot you can try filing a support ticket, but I assume they'll point you back to Microsoft as this is happening on their end. We'll leave this open in case a community member has a suggestion or related experience.

Best,

Jaycee

Thanks Jaycee. I found a way to create a ticket.

We are having this same issue, but from sending 1-1 sequence emails natively within Hubspot. Sometimes after sending 5 emails the email address will become restricted. It's frustrating and frankly ridiculous. And it's absolutely a Hubspot issue.

We have the proper DNS settings applied and it shows connected in Hubspot settings, and have been using Hubspot for years without this issue. I have another domain that sends 4x the volume on Hubspot and is not having this issue. The only difference between the two is the one that is having the issue is a GoDaddy MS365 rather than purchased directly from MS.

That doesn't surprise me about your different experience with the Godaddy M365 account vs Microsoft. Obviously a different set of rules in place. My gripe is that the rules are not published, at least anywhere that I can find. I believe what we are seeing are internal and unpublished policies/settings at Microsoft. It makes it impossible to communicate the issue to anyone at Microsoft that might be able to help.

We have the same issue. For some weeks now, Microsoft has been blocking Hubspot mailings. After forty or so emails, it blocks the sending and then blocks the user's inbox and puts them in a restricted entity.

Are you on GoDaddy for MS emails?
