I don't know what it is called, so I can't search for it on this forum or on Google. What I need to know is the location of the file that holds the ability offer up a previously entered email addresses as a suggestion when you start to type in an email address in the new email TO: field. I think it had something to do with the personal address book, but that file didn't transfer this ability over to the new laptop computer. This is totally annoying the new laptop user.

How do I move this email address ability from an old laptop PC to a new laptop PC?

We have Windows XP Pro, Outlook 2003 on both laptops.


You are looking for the "Outlook 2003 Autocomplete Cache".

You can find the file in:
C:\Documents and Settings\<your username>\Application Data\Microsoft\Outlook

Default name is 'Outlook'.

If you are unable to see it, try this for Windows XP:

* Click Start.
* Open My Computer.
* Select the Tools menu and click Folder Options.
* Select the View Tab.
* Under the Hidden files and folders heading select Show hidden files and folders.
* Uncheck the Hide protected operating system files (recommended) option.
* Click Yes to confirm.
* Click OK.

What is the file extension it uses?
