Start Outlook 2007

Select Export to a file in the Import and Export Wizard

Press Next->

Select Comma Separated Values (Windows) as the export format

Press Next->

Select the folder which contains the contacts' email addresses you wish to modify. Often named, simply, Contacts

NOTE: If you have more than one Contacts folder, you will have to repeat this whole procedure for each one separatelly.

Press Next->

Choose a filename and location (e.g. in My Documents) and make a note of these details - you will need to locate the file later. The filename should have a CSV extension (file type), e.g. "MyContacts.csv"

Press Next->

Confirm the action by pressing Finish

NOTE: You need not make any special field mappings.

Start Notepad or Wordpad (not Word) or another simple Windows text editor from the Start Menu

Choose File | Open from the menu

Find and select the CSV file you created when exporting from Outlook

Choose Edit | Replace from the menu

NOTE: It is recommended that you do NOT edit the file manually - manual changes can create errors

Enter
cwimail.sh in the Find what field
and
helanta.co.sh in the Replace with field

• Take care to spell these entries correctly
• Leave Match case unchecked

Press “Replace all”
(Notepad won’t tell you it has done anything, so you might wish to check in the text for yourself that changes have been made)

Close the Replace dialog box,
Save the file. (Do not forget this!)
Exit Notepad.

Activate Outlook again

Select Import from another program or file in the Import and Export Wizard

Browse for and select the same CSV file you created and edited earlier as the file to import

Check the Replace duplicates option

Select the destination folder.

This should be the same folder you exported originally, but if you choose a different folder, unpredictable results will follow.
