SYMPTOMS

When you send an e-mail message in Microsoft Office Outlook 2003 to a recipient that is selected from the Outlook nickname cache, the e-mail address of the recipient is displayed as SMTP:????????.

Note This problem may spread to other recipients when the recipients reply to your e-mail message.

CAUSE

This problem may occur if the Outlook nickname cache file is corrupted on the sender's client computer.

Specifically, this problem may occur if the recipient's e-mail address is stored as an ANSI string in the Unicode PR_SMTP_ADDRESS_W (0x39fe001f) property field in the Outlook nickname cache file.

This kind of Outlook profile corruption generally occurs when the Exchange Profile Update tool (Exprofre.exe) is not run after a cross-site mailbox move. You must run this tool after cross-site mailbox moves. For more information about Exprofre.exe, click the following article number to view the article in the Microsoft Knowledge Base:
