Exchange 2007 550 550 5.1.1 User unknown (state 14)

Hello Experts,

When I create a new Mailbox on the Exchange 2007 server you are unable to send to that Mailbox from the “Outside World”. For example, if you try to e-mail user@domain.com  from the outside world you will get the following error message (550 550 5.1.1 User unknown (state 14)). Here are a couple of things that get me. Number one you can e-mail out (Send) from that account to the outside world, however if the recipient replies or creates a new message to that account they get the message above. Next, this just started happening all of the sudden today. Also, note that I just created another account yesterday and had no issue, but today I do. Weird??  Any ideas what would be causing this??

I guess you have an antispam/mail relay between the "outside world" and your exchange server, this is were you shoud be looking.

if internally you can send him on his new email address then exchange has nothing to do with it and this error is not, as far as i remember, an exchange error

Akhater, thank you for your quick response.

Sorry, I forgot to add that there is an Edgeserver between the Exchange server and the outside world.

when you say edge server you mean exchange edge ?

Please just have a look.
Bad destination mailbox address.  5.1.1 is the most common Exchange 2007 NDR; there is a problem with the recipient address

Hey guys,

Sorry for the late response.


Akhater,

Is this what you mean...We have our Exchange Server then the Edge Server then Outside world?? The Exchange Server and Edge Server are two different boxes.



SatyaPathak,

Thank you for the link. Although it doesn't really help me in this case, but it does have a ton of information there, so I will be adding it to my collection and reading over the site more later.


Ok, I fixed the e-mail issue for said user account. Dang typos will kill you every time. I missed one letter on the "User Logon name (Pre-Windows 2000)" and that was messing it up for whatever reason.


Now here is my other problem which is a two part question. Let's say I want to take "User A" (The one we have been talking about) and make it so when someone e-mails that address it will go to three different people. I would think you would create a "Distribution Group" for this. However, when I do this and add "User A" and "User B" to that group the e-mails keep going to just "User A". Can you give me a step by step on how to accomplish this and then may be I can figure out where I am going wrong??

The second part is can you e-mail just a Distribution Group from the Outside world??

Hi Justin,

If this problem was solved I really suggest you close this question and start a new one.

this being said you can just make it a user and forward his mailbox to a distribution group or make it a distribution group alltogether

Akhater,

Thank you for your response.


The only reason why I didn't close this question and open another one is because this is all part of my same issue. Let me word it another way because this is what prompted me opening this question to begin with.

I need people from the outside world to be able to e-mail the following address let's say user@domain.com, but I need those e-mails to go to three different people.

What happened was when I created that one user and then a mailbox for user@domain.com all of the sudden I could not e-mail that user from the outside world (Which is what prompted my main question at the top). I got that issue (Part 1) resolved but I can't get the e-mails to go to two users as I described in my last post.

From your last response I take it you know a better way to accomplish this task?? Could you explain to me how to go about this.

option 1 is to create a distribution group and make these 3 users members of it. then emails sent to this group will go to all 3 users. just make sure to open EMC -> recipient configuration -> distribution group. find the group -> right click properties -=> mail flow settings -> message delivery restriction and REMOVE the tick from "require that all senders are authenticated"


option 2 is to keep this guy as a user and to create a distribution group containing the other 3 users (or 2?) then go to EMC -> recipient config -> mailboxes find the user -> right click properties -> Mail flow settings -> delivery options and click on "forward to" and select the distribution group you created

Hope it helps

Akhater,

Ok, "Option 1" is really what I was wanting to do in the first place, so thank you for those steps. When I create the new "Distribution Group" (Let's say Test1234@domain.com), and remove the tick in the box that says "require that all senders are authenticated" that all goes fine. Now if I send an e-mail to Test1234@domain.com I get back an NDR that says "550 550 5.1.1 User unknown (state 14)" What am I missing??

can email the group from inside ? it looks like you have an edgsync issue

go to EMC and run Test-EdgeSynchronization -VerifyRecipient Test1234@domain.com

Yes, and it goes to the correct member (Me In This Case) as well.


Ok, I will give that a shot on Tuesday when I get back in the office, and post the results.

Results to question above,


Name                                       Name of EdgeServer
LeaseHolder                            Name of ExchangeServer
LeaseType                               Option
ConnectionResult                    Succeeded
FailureDetail                            This Is Blank??
LeaseExpiry                             7/6/10  7:55:27 AM
Last Synchronized                   7/6/10  6:55:27 AM
CredentialStatus                      Skipped

TransportConfiguration            Skipped

SendConnectorStatus              Skipped
MessageClassificationStatus    Skipped
RecipientStatus                         Synchronized
CredentialRecords                     Number of credentials 3



When I sent another test e-mail this morning from the Outside World it went through fine and went to the proper "Members". So, I guess my last question does it normally take this long to start working properly? It dosen't really matter I am just curious for the future.

the short answer is that it should get synced with the edge, so as long as running

Test-EdgeSynchronization -VerifyRecipient Test1234@domain.com
doesn't return RecipientStatus                         Synchronized

you will not be able to send him emails.

you can force edgesync by running start-EdgeSynchronization and test again
