Microsoft Exchange to Microsoft Hotmail

Hi,

Our email messages from Microsoft Exchange to Microsoft Hotmail are leaving our system but are not being delivered to hotmail addresses. All was fine until recently. This has come up in this forum previously, was there a resolution?

Thank you.

Hi Pat,

Yes, there are a few causes and solutions for this problem.

Can you check your outgoing mail logs? What do they say for the deliveries?

Is your email being accepted by Microsoft, or is it being deferred or rejected with a specific error message?

Also, what is your outgoing IP address? Do you have a dedicated mail server, or do you use a shared relay for sending your email?

Hi. Deliveries are complete. There are no rejection messages. 159.134.198.135. Dedicated.

I'm not seeing a spam problem when checking the reputation of that IP address - Sender Score | Return Path

I'd jump straight to contacting the Microsoft postmaster team. Open a ticket with them using this link: https://support.microsoft.com/en-us...rt_1.0.0.0&wfname=capsub&productkey=edfsmsbl3

They'll ask you a lot of questions about the types of email that you're sending, samples of your logs etc. Most issues are generally fixed within 48 hours if you can provide details and they agree that you're a good sender.
