Что такое адрес x500 exchange
Будучи основанным на спецификациях X.500, каталог сервера Exchange не следует им в области использования протоколов передачи данных и двоичного формата потоков данных. Однако с точки зрения реализации объектного хранилища и разделения функций между DSA и DUA, Exchange может вполне считаться воплощением канонической модели каталога X.500. На рисунке 1.13 приведена схема информационного дерева каталога Exchange Server, содержащего все необходимые компоненты классического каталога, включая корень, контейнеры, листья и схему данных.
Каждый объект каталога имеет уникальное имя в каталоге, полное и относительное характерное имена. Формат характерного имени поясняет рисунок 1.14. Характерные имена объектов, таких как пользовательские ящики, списки рассылки и т.д., могут использоваться в качестве их почтового адреса во внутреннем формате Exchange. Следует, однако, помнить, что внутренние адреса имеют силу только в том случае, если адресуемый объект находится в пределах той же организации, что и отправитель.

Exchange использует метод репликации фрагментов каталога, т.е. каждый сервер хранит локальную копию каталога организации. Запросы от пользовательских агентов каталога обрабатываются локально во всех случаях, кроме обращений к общим папкам. Если сервер не имеет на себе запрошенной копии, он на основании данных каталога, переадресует клиента к DSA сервера, на котором копия папки присутствует.
Каждый сервер обслуживает фрагмент, состоящий из четырех неперекрывающихся пространств именований: организации (Organization), площадки (Site), настроек (Configuration) и схемы каталога. Назначение каждого из них будет рассмотрено далее.

Надо добавить адрес X500 для проблемного пассажира
To resolve this issue, use the following method.
Create an X500 proxy address for the old LegacyExchangeDN attribute for the user
To create an X500 proxy address for the old LegacyExchangeDNattribute for the user, make the following changes based on the recipient address in the NDR:
X500:/O=MMS/OU=EXCHANGE ADMINISTRATIVE GROUP (FYDIBOHF23SPDLT)/CN=RECIPIENTS/CN=User-addd-4b03-95f5-b9c9a421957358d
Что такое адрес x500 exchange
Question
I recently recreated an Exchange 2007 user mailbox, and now recipients replying to old emails are getting this NDRs:
I did some research and apparently, I need to create a custom X500 address. I tried doing that using the format below, but the user is still getting NDRs.
Someone said it’s case-sensitive, but still getting NDR’s.
Can somebody tell me what I’m doing wrong?
Thank you in advance.

The x500 is typically using the alias or cn unless there was some customization. Just add two x500 addresses like below, one of them will likely be the correct one.

The ideal method would be not to delete the original mailbox. Create a new one, move all data etc and then forward the old to the new. Then it wouldn’t be a problem.

try adding the legacyExchangeDn of old mailbox as x.500 address
Something like:
x500:/o= /ou= /cn=Recipients/cn=
legacyExchangeDN:/o= /ou= /cn=Recipients/cn=
Well I just tried both custom addresses:
x500:/o= /ou= /cn=Recipients/cn=
L egacyExchangeDN:/o= /ou= /cn=Recipients/cn=
but I’m still getting the NDRs. I’m confirmed that there are no typos. I even tried from OWA and still getting the same NDR.
Any other suggestion?
does the user get it or does it bounce?

Just tried. Still getting NDR.
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##
Was this originally a 2003/5.5. org?
Compare the x500 you entered to the legacyExchangeDN of another mailbox.
Can you post the exact x500 address you added ( obscure the Org Name and alias if you want, but not the actual construction of the address)
Remember, either the admin group, recipients container or alias changed when you recreated the mailbox. The x.500 address you add as a custom address has to be what it was BEFORE. So most likely, it was referring to a legacy admin group, or you created a new alias when you created the new mailbox (SamAccountName versus First.Last etc..)
Here are the two x500 custom addresses that I entered:
And yes, the user was originally a member on the Exchange 5.5 org, then upgraded to 2003 and now 2007.
Thank you in advance.

Ok, the 2nd one is not a proxyaddress, so you can remove that.
Assuming the OU is set correctly ( NY was the legacy Admin Group?), and the Org Name is correct, then I would focus on the cn= Typically the 5.5 alias is going to be the original sAMAccountName and not user@domain.com
Is that really what it was?
Are you sure cn=user@domain.com is correct? Typically the cn= john doe. The @domain.com isn’t typically there unless there was some customization going on.
When you looked up an existing user’s legacyexchangedn did it show @domain.com?
James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
Well, I think the OU is NY. Below is the NDR so that’s what I’m referencing.
I will try using the sAMAccountName, but how do I get the sAMAccountName?

It would be the account they logon to the domain with using the domain\user convention. Whatever «User» is.
If you look at other accounts legacyexchangeDN values, you can confirm that.
That IMCEAEX-_O=COMPANY_OU=NY_cn=Recipients_cn=User@domain.com isnt really what their legacyExchangeDN value was nor is it a valid address. Its the encapsulated address of that account referring to the default recipient domain.

Or an Employee Number or JohnD or etc.. 🙂
OMG!! It’s working!! The full username did the trick. Woo-hoo.
Glad you got it figured out! 🙂
YOU my friend, hit the nail on the head with that one. You’re some sort of an exchange genius!
I had a problem where /O=ExchangeOrgName/OU=NY/cn=Recipients/cn=John-DoeAC422F48510784669C5B30BD0FCDAA was what I got using the Get-MailPublicFolder
| Select LegacyExchangeDN and used that as the X500 address, and it didn’t work.
I then just removed the random numbers from the end so it looks like this /O=ExchangeOrgName/OU=NY/cn=Recipients/cn=John-Doe like you suggested and added it as an extra X500 address and voila, it works!
We had the same issue on Exchange 2010, and this almost worked for us: /o=CompanyName/ou=Site/cn=Recipients/cn=User@domain.com
What we needed to add was extra information from the bounceback email. Here is the bounceback email:
Delivery has failed to these recipients or groups:
(full name of user is displayed here, as it was entered in AD)
The e-mail address you entered couldn’t be found. Please check the recipient’s e-mail address and try to resend the message. If the problem continues, please contact your helpdesk.
How to Edit and Add a Legacy X500 Address Into The New Mailbox
If for any reason if you move an SMTP address from one mailbox to another, your help desk start to receive complains that certain users (Not All) receive the following bounce backs when sending messages to that mailbox:
Here is the reason for this bounce back:
Internal exchange messages inside the organization normally have the recipient’s information resolved to LegacyExchangeDN attribute (Underlined in Red).
In this case since this address was assigned to a different mailbox the old LegacyExchangeDN value is changed; so, if a user who has sent an email to that address that was associated with the old mailbox sends an email after the change, they will get this bounce back because the LegacyExchangeDN value is cached on their outlook. There is no problem for people who never sent to that address before.
Now if you see the bounce back Diagnostic Information message above you see that it provides you with the Legacy Exchange DN (Boxed in Red), Or you can access that by clicking on the name in the body of bounce back message:
IMCEAEX-_o=COSTARGROUP_ou=Exchange+20Administrative+20Group+20+28FYDIBOHF23SPDLT+29_cn=Recipients_cn=8da2b5094c364af7bb8861ce9064020a-ransnary@domain.com
We need to add the above X500 to the new mailbox, the tricky part is that the above x500 is in an encoded (Messed Up) format and we need to clean up to bring it to the right format. here is how it’s done
Step-by-step guide
2. As you can see you will notice some numbers like +20,+28,+29
Convert +20 with a Space
So now, replace the values as described and you should get the following:
3. Remove the @Domain.com and just keep the username
Now simply add the final cleaned up proper x500 address to the mailbox via exchange management shell:
Sometimes you may need to update the legacyexchagedn attribute itself as well. unlikely but I have run into that situation as well.
Prepare for a Migration: What is the X500 email address?
Dec 18, 2018 by Mike Weaver
The X500 email address, or the X500 Proxy Address, is one of the most important “tricks” of the data migration trade. Regardless of Exchange Version, including Exchange 2010, Exchange 2013, Exchange 2016, or Exchange Online in Office 365, this trick still applies today.
When moving from one environment to another, calendars can be a major challenge. This stems back to the very early days of Exchange.
What exactly is the problem?
Back before Exchange was integrated into Active Directory, Exchange used the Legacy Exchange DN for internal recipients. Because of this, internal recipients are actually stored in content, like calendar invites.
The result is that if someone updates a calendar invite after it has been moved to another environment, the internal attendees will get a nasty undeliverable (NDR). The business result is people going to the wrong place at the wrong time, confused users, and frantic emails saying, “DELETE THE BAD INVITE NOW!!”
How To Add X500 Email Addresses
So the bad news is that if you are here right now, it can be hard to fix this. You need to collect the Exchange Legacy DN from the source before the move to make it easier. You can fix this as they come in by just taking the Exchange Legacy DN from the NDR, but that won’t scale.
The good news for Quadrotech’s Office 365 reporting customers is we collect this for you. For our Microsoft 365 tenant migration customers, you are not likely reading this as we do this entire process by default!
So…here is one method to collect the Exchange Legacy DN before migration and three ways to correct it after migration. (with some other helpful info!)
Source Preparation
This is one of my favorite scripts. It has been added to over the years. This script will collect the following:
You’re probably wondering how do I run this collection script?
So I’ve provided you with the script at the bottom of this article!
Always test all scripts in a test environment!
Target Correction
Method 1: Active Directory Users and Computers (ADUC)
If you just have a few accounts to change or want to investigate the issue further, you can use ADUC to do this, with Advanced Features Turned On.
Method 2: Exchange Admin Console
You can also add the X500 Proxy Address in the Proxy Address Section of Microsoft Exchange. In this example, I will do this in Exchange 2016
1. Log into the Exchange Admin Center
2. Click on Recipients
3. On the mailbox screen search for the user, you want to update and open the properties of the account
4. Choose the email addresses tab on the left-hand side
5. Click the + button
6. For the address type choose custom and type “x500
7. In the email address, copy and paste the Exchange Legacy DN
9. Wait for replication
Method 3: PowerShell
You can also do these functions in PowerShell using the Active Directory Module. This script can be used to add the X500 Address address.
Login to a computer with the Active Directory tools installed. You can import the module (import-module or just launch the “Active Directory for Windows PowerShell” application
As always, practice on a test user first! If for some reason you make a mistake, you can edit the addresses using the attribute editor in the section above if you need a visual.
