This article describes how to modify recipient policies in
Exchange 2003 to determine how a user's e-mail address is
generated. When you use the procedure that is described in this article to modify a recipient policy, you can define specific settings that allow you to
meet the naming conventions that are required for your organization.
By default, Exchange 2003 has one recipient policy that is named "Default Policy.” Default
Policy generates Simple Mail Transfer Protocol (SMTP) e-mail addresses in the following format, where user_name
is the Exchange alias property
of the user, and domain_name
is the Microsoft Active Directory directory service domain name:
Do not modify Default Policy if you
want to use the replacement strings that the following procedure describes to generate your SMTP address. If you want to use replacement strings, you have to create a new recipient policy. If you try to modify Default Policy, you may experience problems if Default Policy is based on attributes such
as given name or surname.

To modify a recipient policy:
- Start the Exchange System Manager. To do this, click
Start, point to Programs, point to
Microsoft Exchange, and then click Exchange System
- Double-click Organization, double-click Recipients, and then click Recipient
- Double-click the policy that you want to change.
- Click the E-Mail Addresses tab, and then
edit the appropriate SMTP Generation rule by using any of the
following replacement strings:
- %s : Surname (last name)
- %g : Given name (first name)
- %i : Middle initial
- %d : Display name
- %m : Exchange 2003 alias
- %rxy : Replace all subsequent characters x with character y in
username. If x = y, the character will be deleted.
- You can put a number in front of any of the these
strings to define how many characters of the string must be used, for example:
- %1s : Uses the first letter of the surname
- %5g : Uses the first five letters of the given name
- Invalid characters that are contained in a user's name are not
used in the e-mail address (in accordance with Request for Comments [RFC]
If you use the %r replacement string to substitute a valid character for an
invalid character, all of the %r string is ignored. Additionally, %r must be used immediately before a replacement string where you
want to replace characters.
- If you want to replace character "x" with character "y"
in the last name (represented with %s), an SMTP e-mail address is generated as follows:
%g.%rxy%sFor example, if you want to change the user name
"JamesC.Wilson", to "JamesC_Wilson", type the following string:
- If the %rxy string is in front of the whole e-mail
address, character "x" is not replaced by character "y" in the last name.
- In the %rxy string, x can equal blank space. This string can be used to merge spaces in the name with a valid character.
- You cannot use the %rxy string as %r to remove
manually typed periods from the Initials field in Active Directory Users and
Computers. You may want to remove the manually typed period from the
Initials field in Active Directory because this text also affects other
The following example lists the SMTP address that is generated when you use the replacement strings for the user logon name "jwilson":
Display name: James C. Wilson
Given name: James
