What is this:


E-mail Address Policy/Policies


How can you use e-mail address policies to remove unwanted e-mail addresses?

You cannot.

EAPs can be used to add e-mail addresses, but they never remove e-mail addresses.


In an EAP address format, what does this variable mean?


Given name


In an EAP address format, what does this variable mean?


Middle initial


In an EAP address format, what does this variable mean?




In an EAP address format, what does this variable mean?


Display name


In an EAP address format, what does this variable mean?


Exchange alias


In an EAP address format, what does this variable mean?


Use first X letters of surname


In an EAP address format, what does this variable mean?


Use first X letters of given name


If you don't specify an e-mail address format in an EAP, what will the resulting e-mail address be?

It will default to use the user's Exchange Alias. For example,


What is the default EAP and how does it work?

When Exchange is installed, it creates one default EAP for the organization.

By default, it will just assign the default Accepted Domain to all recipients. That Accepted Domain will be whatever the AD Forest name is.


How are EAPs matched to recipients?

You configure queries in the policy, for example, what text is in the "Company" field of the user.

Policies are also configured with a priority.

If more than one policy matches the recipient, the highest priority policy wins.

Note: The HIGHER the priority number, that means it will win. Unlike some other Microsoft systems where a lower number wins.


If there are multiple MX Records configured for a domain, how will Exchange pick which one to send outgoing e-mail to?

Each MX record includes a Preference value. The record with the LOWEST preference number is what Exchange will attempt to connect to first.


What is a Send Connector?

Send Connectors are used to route e-mail to external recipients.

At least one Send Connector is required per organization, for sending mail out to the internet.


What reasons would there be to configure multiple send connectors in an organization?

Send connectors are shared for all recipients and domains in an organization. You don't need to configure separate send connectors for seperate parts of your organization.

But, additional Send Connectors can be used for:

• Controlling e-mail delivery to specific external domains

• Securing mail flow to partner organizations

• Fault tolerance; so you have multiple out-bound routes from your organization


What is the Edge Transport Server Role?

• An optional server role for Exchange organizations.

• You would typically only install it if you need a specific feature, or to satisfy a security policy.

• It handles SMTP communications (e-mail transport) going out to, and coming in from, the internet.

• It is not involved in any client connectivity or other connectivity.

• It is designed to be placed in a perimeter network.


Why might you use an Edge Transport Server?

Organizations that require no direct connectivity between the internal network and the internet could use an Edge Transport Server in their DMZ.


What transport agents are available to an Edge Transport Server?

• Address Rewriting Inbound Agent

• Address Rewriting Outbound Agent

• Attachment filtering

• Antispam agents


What are the DNS requirements involved in setting up an Edge Transport server?

• The Edge Transport server must be able to resolve Mailbox server names
– either Point server to internal DNS, or add entries to hosts file.

• The Mailbox servers must be able to resolve Edge Transport server names
– best done by manually adding A records to internal DNS zone

• Edge Transport must be able to perform public DNS lookups for MX records.


What are the firewall requirements involved in setting up an Edge Transport server?

• TCP 25
– There must be bi-directional SMTP access between Edge Transport servers and internal/external e-mail servers.

• TCP 50636
– Outbound Edgesync access from Mailbox servers to Edge Transport servers.

• NAT inbound SMTP connections to the Edge Transport server instead of the internal mailbox server.


What port does Edgesync use?

TCP 50636


What is ADLDS?

Active Directory Lightweight Directory Service


What are the server prerequisites for installing the Edge Transport server role?

Just one:

Active Directory Lightweight Directory Service (ADLDS)


What is the Command Prompt command to install the Exchange Transport Server Role?


• /m specifies the "mode"

• /r specifies "role"


What is EdgeSync?

EdgeSync is the process that handles synchronization of data from AD to Edge Transport Servers, where it is stored in the ADLDS instance on the Edge Transport Server.

It is necessary because Edge Transport servers, being on a perimeter network, should not have inbound access to a domain controller.


What is an Edge Subscription?

For EdgeSync to connect an Edge Transport server to the internal Exchange organization, an Edge Subscription must be configured.


What does EdgeSync synchronize and create?

EdgeSync synchronizes:

• Topology Data
(about the internal Exchange organization)

• Configuration Data

• Recipient Data

Also, when the Edge Subscription is first created, it creates "EdgeSync" send and receive connectors on the mailbox servers for internet mail flow.


What tools can be used to manage a Edge Transport server?

There is no GUI or WUI. All administration must be performed through Exchange Management Shell.


What is Address Rewriting?

A feature of the Edge Transport Server role,

It allows for changing the "from" or "to" e-mail addresses on inbound and outbound e-mail through the use of rules.

It is rarely used in the real world, usually limited to scenarios of rebranding or mergers.

Note: Even though it can change the "from" email address, it will not remove the original sender's address from the header, so that NDR can be returned.


What are examples for the use of Address Rewriting?

• Changing a single email address to another address
– to present a single, public alias for a particular sender
– to consolidate a team of agents to have a single public address, such as "Sales"

• Changing a single domain to another domain
– useful during rebranding

• Multiple sub-domains to a single domain
– useful when multiple internal subdomains are used, but you want to unify them for external mail.
