This is not an elegant solution but it can be done this way:In OWA, start a new email, so that your auto complete contacts appear in a list. SELECT ALL of the contacts, click 'To' to plug all the contacts you selected into an email header. From within the email header, copy the list of contacts, then paste the list into Word (to clean up).
Use Word's Find/Replace to clean up the contact list, using macros, if possible. Once you have the contacts in list form, you can massage the data to be imported into some email client, such as Outlook, which is the one I use.
Outlook 2010 can import Excel data and turn it into Contacts data using the "File/Open/Import/ Import from another program or file" commands.
The contacts data must be saved in Excel 2003-2007 file format, and the data columns must be Range Names for the import to work in Outlook. Outlook will allow you to map each Range Name in the spreadsheet to a field name in the Outlook Suggested Contacts data file. The email addresses will now be automatically filled in as the user types one of the imported contacts when creating new email with Outlook 2010.
