How to Configure Exchange to Automatically Modify SMTP EMail Addresses for new users and existing users:

With Microsoft Exchange 2003, you can tell Exchange server to automatically add pre-formated SMTP email address for existing and new Exchange accounts.

To add a formated SMTP email address:

1. Connect to the server where Exchange is installed.
2. Run "Exchange System Manager".
3. In the left side pane, Expand menu "Recipients".
4. Then "Recipients Policies".
5. In the right side pane, right-click "Default Policy" and select "Properties".
6. Clic on "E-Mail Addresses (Policy) and click the "New..." button.
7. From the "New E-Mail address" window, select "SMTP Address" and click "OK".
8. Position the cursor in the "Address" field and type in the domain name in this format:
   %g.%s@domain.com.
9. Make sure to leave the check mark next to "This Exchange Organization is responsible for all mail delivery to this address" and click "OK".
10. By default the new SMTP address will not be enabled. Click the check box nest to the newly added domain and click "OK".
11. The e-mail Addresses of type(s) [smtp] have been modified.
    Do you want to update all corresponding recipient e-mail addresses to match these new address(es)?
    Click yes if you want to ADD all Exchange users a new e-mail address corresponding to the %g.%s@newdomain.com
    Click no if you want to manualy add e-mail addresses to selected accounts.

Here is the list of variables you can use:

1. %g = given name (first name)
2. %s = surname (last name)
3. %i = middle initial
4. %d = display name
5. %m = Exchange 2000 or 2003 Alias
6. %rxy = Replace all subsequent characters x with character y in username. If x = y, then the character will be deleted.

You can place a number in front of any of the preceding switches to define how many characters of the switch should be used, for example:

1. %1s = Uses the first letter of the surname
2. %3g = Uses the first three letters of the given name
3. %1g%s = Uses the first letter of the given name and the given name

The one I use the most often is:

1. %g.%s = mark.smith@sertec.ca
2. %1g%s = msmith@sertec.ca
3. %g = mark@sertec.ca
