BirdieSync™ allows synchronization of your contacts, appointments, tasks and mails between Pocket Outlook™ on your mobile with Thunderbird™ and Lightning™ or Sunbird™ on your PC. Based on ActiveSync® technology and the Windows Mobile Device Center, items are synchronized as soon as your mobile is connected to your PC. Every creation, modification or deletion of a contact, appointment, task or mail on one of the devices are automatically transferred to the other one. So you only have one address book and calendar to manage and you can consult and manage your mails on your mobile. Your information is always up to date.
