How do I export my Thunderbird address book to Outlook.com

The outlook import doesn't refer to Thunderbird and won't accept an ldif file.

Export the file as a Comma Separated file. .csv file Most applications accept this file type.

Thanks. I did this and only the contacts' names were transferred - no e-mail addresses of telephone numbers!

Still not working! I edited the file in Excel, just leaving first and last names and e-mail addresses in columns 2,4 & 47 as you suggested but still only succeeded in transfering the names. When I go to save the edited csv file I receive a message saying that the file may contain features that are not compatible with CSV (comma delimited). I was unable to find the Excel module in Outlook.com I'm beginning to think I should stay with Thunderbird. I thought I'd use Outloook.com as I use different PCs on my travels.

Thanks, that worked - but what an effort! Apart from copying and pasting the addresses I found that 25% of my contacts hadn't been copied via the CSV file! I hope someone fixes the problem for future transfers.
