Exchange attributes in ad

Exchange Server includes 15 extension attributes that you can use to add information about a recipient, such as an employee ID, organizational unit OUor some other custom value for which there isn't an existing attribute. In earlier versions of Exchange, if you wanted to store this information in Active Directory, you had to create an attribute by extending the Active Directory schema.

Schema extension requires planning, procuring object identifiers OIDs for new attributes, and testing the extension process in a test environment before you implement it in a production environment. Exchange Server doesn't let you use schema extensions in recipient filters that are used by address lists, e-mail address policies, and dynamic distribution groups. These attributes aren't used by any Exchange components. They can be used to store Active Directory data without having to extend the Active Directory schema.

Don't use non-Exchange tools to edit these attributes because they might be used for future Exchange features. You don't need to build custom controls or write scripts to populate and display these attributes. You can filter and reuse the attributes, as attributes are filterable properties that can be used in the Filter parameter with recipient cmdlets such as Get-Mailbox. They can also be used in the EAC and the Exchange Management Shell to create filters for e-mail address policies, address lists, and dynamic distribution groups.

Starting with Exchange Service Pack 2 SP2five multivalued custom attributes were added to Exchange to allow you to store additional information for mail recipients if the traditional custom attributes didn't meet your needs.

You can specify multiple values as a comma-delimited list. The following cmdlets support these new parameters:. For more information about multivalued properties, see Modifying multivalued properties. A common scenario in many Exchange deployments is that of creating an e-mail address policy for all recipients in an OU. The OU isn't a filterable property that can be used in the RecipientFilter parameter of an e-mail address policy or an address list.

Dynamic distribution groups have an additional parameter that you can use to restrict it to recipients in a particular OU or container. If the recipients in a particular OU don't share any common properties that you can filter by, such as department or location, you can populate one of the custom attributes with a common value, as shown in this example.

With that done, now you can create an e-mail address policy for all recipients that have the CustomAttribute1 property that equals SalesOU, as shown in this example. When creating dynamic distribution groups, email address policies, or address lists, you don't need to use the RecipeintFilter parameter to specify custom attributes.

This example creates a dynamic distribution group based on the recipients whose CustomAttribute1 is set to SalesOU. You need to use the IncludedRecipients parameter if you use a Conditional parameter. In addition, you can't use Conditional parameters if you use the RecipientFilter parameter.

If you want to include additional filters to create your dynamic distribution group, email address policies, or address lists, you should use the RecipientFilter parameter. When using the ExtentionCustomAttributes parameters, you can use the -eq operator instead of the -like operator.

We have never had an on-prem exchange server in this environment. The issue I am having is that all newly created Distribution Groups are defaulted to not allow external people to email these distribution groups. Before, I could go right into the Admin Portal and check a box to allow this, however, with the directory sync, everything has to be done within Active Directory. The problem is that the attribute within the Attribute Editor does not have the necessary Exchange attributes that allow for this.

Is there a way to get the necessary attribute msExchRequireAuthToSendTo without implementing on-prem exchange or extending the exchange attributes via the installation media? I've created several that way and have no trouble changing settings. Figured it out. I think you would need to extend AD on-prem the achieve the required result. However, I might be wrong. Did you try opening a ticket with Office support?

It's free. I think you are right based on all the researching I have been doing. To my knowledge, this doesn't require exchange but rather only it's installation media to get these attributes.

It is also not supported by Microsoft, so I'm wondering what their official support is? I mean it seems wonky that you shoot yourself in the foot by implementing DirSync if you don't first have on-prem exchange!

To the best of my knowledge the only way MS suggests and recommends performing attributes update is through Exchange Hybrid. In majority of the cases, this is utilized when a company migrated from on-prem to Office, however in your case, you might have to perform the implementation of Exchange Hybrid as a "backwards" compatibility with what you looking to achieve.

However in order to be able to change anything, you need to have those additional attributes for the relevant objects to exist in AD. The following article include the list of attributes synced from on-prem to Office, it includes the attribute you need as well. Have a look at the following info: Office and Dirsync: Why should you have at least one Exchange Server on-premises. Probably applies to your case: Error when you try to restrict senders to send message to specified distribution group in on-premise organization that has no Exchange server.

To summarize: 1. You probably would need to perform at least the extension of AD with Exchange attributes. Okay, so here is the rundown for those folks out there that may have this similar situation. There are 3 ways of resolving this issue with caveats :. To continue this discussion, please ask a new question. Adam CodeTwo.This topic lists the attributes that are synchronized by Azure AD Connect sync.

The attributes are grouped by the related Azure AD app. A common question is what is the list of minimum attributes to synchronize. The default and recommended approach is to keep the default attributes so a full GAL Global Address List can be constructed in the cloud and to get all features in Office workloads. In some cases, there are some attributes that your organization does not want synchronized to the cloud since these attributes contain sensitive or PII Personally identifiable information data, like in this example:.

In this case, start with the list of attributes in this topic and identify those attributes that would contain sensitive or PII data and cannot be synchronized. Then deselect those attributes during installation using Azure AD app and attribute filtering. When deselecting attributes, you should be cautious and only deselect those attributes absolutely not possible to synchronize.

Unselecting other attributes might have a negative impact on features. This group is a set of attributes used as the minimal attributes needed for a generic workload or application. It can be used for a workload not listed in another section or for a non-Microsoft app. It is explicitly used for the following:. This group is a set of attributes that can be used if the Azure AD directory is not used to support OfficeDynamics, or Intune.

It has a small set of core attributes. A Windows 10 domain-joined computer device synchronizes some attributes to Azure AD. For more information on the scenarios, see Connect domain-joined devices to Azure AD for Windows 10 experiences.

These attributes always synchronize and Windows 10 does not appear as an app you can unselect. A Windows 10 domain-joined computer is identified by having the attribute userCertificate populated. These attributes are written back from Azure AD to on-premises Active Directory when you select to enable Exchange hybrid. Depending on your Exchange version, fewer attributes might be synchronized.

Device objects are created in Active Directory. These objects can be devices joined to Azure AD or domain-joined Windows 10 computers. Learn more about the Azure AD Connect sync configuration.

In order to add those attributes the Active Directory Schema must be extended to include Exchange attributes.

The process below will only extend the schema and Exchange is not fully installed. In our example our Active Directory server is Server R2 and we are using the Exchange setup files.

If you are using an older server, such as Server R2, you may have to use the Exchange setup files which can be found in a link below. Once the download is complete run the ExchangeServer or ExchangeServer file and you should see the disc image file open as a Drive: as shown below.

In our example the Drive is E:. Now that the drive is attached we need to start the extension of the AD Schema. Our command starts with E: because our drive in step 2 was E: If your drive is different replace E: with your drive letter.

Once the Schema is extended you should see a message that says "The Exchange Server setup operation completed successfully" as shown in the following screen-shot. At this point open Active Directory Users and Computers and double click a user. Next click the Attribute Editor tab and scroll down to verify the Exchange attributes are now listed you can specifically look for the msExchHideFromAddressLists attribute as shown below.

I contacted Microsoft tech support about this and they said there was no way to override the settings in because they were synced so i would have to add the extensions on my AD server. I don't think you need to actually install Exchange to accomplish this. I don't necessarily see this as particularly risky. Here's a link to details on how to extend the Schema for Exchange Server What Microsoft said is right: the sync process is one-way, and some well, a lot of settings can not be managed by Office in your scenario: they need to be configured on your local AD and then synced; however, your environment lacks any Exchange deployment, so those attributes don't even exist in your AD objects.

As joeqwerty said, extending the AD schema by running the relevant step in the Exchange setup setup. However, since you don't have any local Exchange server, you'll have to manually edit those attributes using ADSIEdit or your favourite LDAP editorbecause there will be no Exchange tool to manage them.

All users, groups, and contacts hold Exchange information, including email address, department name, mailbox GUID, and mailbox policy settings. However, it's not unheard of to accidentally delete users, groups, and contacts during AD management. If this happens, all email communication with involved users, contacts, and groups comes to a halt, profoundly hindering the organization. So, restoration becomes the highest priority. A recovery operation to restore all deleted or modified Exchange attributes to their original, working state is vital.
