Starting 5 days ago, I cannot successfully send email from Thunderbird to any outlook.com address including my own. My TBird address is on my/friends Outlook.com safe sender list. The emails bounce back from my ISP with error code 421 RP-001 "while talking to mx2.hotmail.com" MY ISP tries to send the emails for 5 days. I receive all the expected Thunderbird/Outlook.com addressed email as usual except to MY Outlook from Thunderbird.

MY ISP says they are not getting blocked by Outlook.com.

PC, Windows 7, FFox,

Are you sending messages with many outlook/hotmail/live recipients, e.g. to a mailing list? If you aren't, perhaps someone else who uses your ISP is doing so. Probably best for you to ask your ISP to contact outlook.com.

I'm sending few than 10 emails a day. The ISP asked me to forward them the transcripts for their review. I did so but they said it was a outlook/hotmail/live issue and not the ISP's. I agree that someone else using the ISP could be causing the issues. I've used the same ISP for 15 years without an email problem. I wish I knew how they could tell by looking at the transcript that it's not their problem.

I will go with this http://www.smtp-error-codes.info/bounce/hotmail/bounce_421_RP-001.php

If you want to forward the entire thing I will look at it, but I think your ISP and the folk at Microsoft need to sort out their issues and not involve their customers.

Thanks Matt, I finally got my ISP to understand that the problem was between them and Microsoft. I used the "Warning: could not send message" email transcripts from my ISP and used several IP addresses they use to route my mail and checked several Websites that search for blocked addresses. I found that several were blocked. Some test emails to my personal Outlook/Hotmail addresses finally went through yesterday in one big batch but everything else now bounces back. I shudder to think how much I've paid them for 15 years of high speed service to only get "it's not our problem" responses. I'll make a reply when they fix it. I've learned a lot working through this issue and think I should be charging them for my research! Thanks again.
