Use the SMTP Address and Custom Address dialog boxes to specify a new e-mail address and address type for the recipient. This dialog box appears when you click Add or Edit on the E-mail Addresses tab in a recipient's property page.

Note:
To open the Custom Address dialog box, on the E-Mail Addresses tab, click the down arrow next to Add, and then click Custom Address.
E-mail address

Use this box to type the new address.

Note:
Exchange validates Simple Mail Transfer Protocol (SMTP) addresses for proper formatting. If your entry is inconsistent with SMTP format, an error message will be displayed when you click OK.
Important:
Exchange 2007 does not validate custom addresses for proper formatting. You must ensure that the custom address you specify complies with the format requirements for that address type. Because X.400 addresses are considered custom addresses in Exchange 2007, they are also not validated. Therefore, you must provide the correct syntax when specifying an X.400 address. For more information about the X.400 address format, see X.400 Message Handling System (X400).
E-mail type
  • Use this box to type the e-mail address type. The e-mail address type cannot exceed 9 characters.

  • The e-mail address type is the identifying proxy information for the e-mail address. Exchange uses this information to determine how to process the e-mail address.

    Note:
    In the SMTP Address dialog box, this box is automatically populated with SMTP and cannot be modified.
  • Examples of custom e-mail types include X400, GroupWise, and Lotus Notes.

  • This box is disabled when editing existing e-mail addresses.
