According to what I understand, they have previously been able to contact our users, but they occasionally receive this error while doing so. We don’t have a hybrid environment or anything like that; we just moved from an Exchange server to Office 365 a few months ago.
Thank you for getting in touch with us. According to your explanation, this problem only affects a few people in your business. Since you listed migrating from an on-premise Exchange server to Office 365, please double-check that the DNS records have been deleted.
In addition, in order to better understand your situation, we need to collect the entire Non-Delivery Report (NDR) email. You can save the NDR as a.msg file and email it to us using the link below.
Thank you for the details you sent in your PM. The email is created by MBX031-W4-CO-2.exch031.domain.local, according to the post. It’s an on-premises Exchange server, not an internet Exchange server. So, can you tell me if your Exchange server is on-premises?

Please assist me. I need assistance! The Beatles visited the United States, and I saw them with two other girlfriends in 1966 (Philadelphia Shea Statium). At the moment, I was 15 years old. We all had medium to long hair, and our faces were covered in dried tears and mascara. It had been a few years since I learned that both of my mates had passed away later in life, and we had all grown apart. However, a sister of one of my recently deceased fr…

Exchange server 2016 mx record setup

A back-and-forth exchange between the client and the server constitutes an SMTP session. The client sends text commands to the server, which the server responds to with numerical codes attached to messages. In our blog post on SMTP Commands and Response Codes, we covered this contact. Since error codes on various servers may have different meanings, you have a few options for fixing the problem. Today, we’ll talk about one of them, the 550 5.1.1 bug, and how to correct it.
As a response to the RCPT TO order, the client usually receives a 550 5.1.1 code. It’s an error code that usually indicates a problem with the receiver server. “User unknown” is the most common error message. This is due to the fact that the recipient address does not exist in the majority of instances. However, there are other explanations and error messages that may be present.

Is this to say that the 550 5.1.1 error code can be triggered by both the receiver and the sending server? Let’s take a look.

Dns error: domain name not found. delivery to the following

Hello, I’ve been trying to figure out what’s going on for a few weeks and have finally given up and asked for help. We recently upgraded from Exchange 2010 to Exchange 2016, and we had never experienced this problem before. I’d like to believe it’s something to do with Exchange 2016, but I’m not sure. We can accept emails from anywhere and there are no problems when external users send emails to a few of our internal addresses. When an external user emails multiple internal users, they will receive the following error for each of the internal users mentioned in their email: #SMTP# [email protected] This only occurs when several email addresses are selected; if the external user emails each address individually or in groups of two, they all arrive at their intended destination. I’ve looked through multiple logs on our Exchange server, but the only one where I’ve found any trace of the emails so far is the SmtpReceive log, which contains the following in regards to the error:
Da Schmoo is a character in the game Da Schmoo. I’m working on having that one out, but it’s been there for a long time and we’ve never had any problems like this before. Furthermore, the mail is arriving at our server, but it appears that our server is unable to locate the recipients until rejecting the message. Would the mails not have gotten through in the first place if it was the secondary mail record? Jasmine
