Hi everyone,

We’re having an issue where emails sent through HubSpot are showing up in Microsoft/Outlook as “Unverified Sender.” This is creating a serious problem for our business because recipients are questioning whether our emails are legitimate.

We’ve already contacted HubSpot support multiple times, but they’re telling us Microsoft needs to resolve it. From what I understand, this may be related to email authentication/DNS setup, but I’m not sure what exactly is wrong.

Has anyone dealt with this before and know how to resolve? I’ve been at this for two weeks :(
