PST File Corruption Due to Damaged Outlook Nickname Cache
 
Microsoft Outlook is a popular and widely used email application, which stores emails and other data in the form of PST (Personal Folder File). You can send and receive emails using Outlook and can use it with Microsoft Exchange Server to create a collaborative messaging environment. But sometimes when you send an email in MS Office Outlook 2003 to a recipient, which is selected from Outlook nickname cache, email address of recipient is shown as SMPT:????????. This behavior might spread to other mail recipients when any recipient replies to your email. Along with this, you may also encounter some error message while opening an email or other item. This is caused by damaged PST file or Outlook profile. To work around such issues, PST Recovery is required.

Such type of Microsoft Office Outlook profile corruption usually takes place when the MS Exchange Profile Update Tool (Exprofre.exe) isn't run after move a cross-site mailbox. You must run this utility after moving the cross-site mailbox.

Mailbox server may refer Outlook to correct server after the mailbox has been moved within an administrative group, but the process does not work properly.
