Hi Raymond,

It's addresses sending to our users. The senders get a 554 error from Hotmail with no description. Our logs on our side are clean, so its a bit of a blackbox. We need some insight from Hotmail's side. Thank you also for the link.

Is it hotmail users sending your users emails that are being rejected, or is it your users sending hotmail emails that end up rejected?

Hey All,

Does anyone have a good contact number for the Hotmail NOC? We've got e-mails from Hotmail to some of our customers being returned the Hotmail sender with a 554 error message fairly regularly. Our logs aren't showing any rejections, so we need to talk to Hotmail and find out what the 554 means on their side (there's no error description). Any help is greatly appreciated.
