Hi AnaisCiprian,
Sorry for the delayed response.
Can you please let me know which firmware version you are running on your handset?
To find out dial *#1234# - the latest firmware should end in C1.
The reason I ask is because the issue you mention of not being able to sync your hotmail folders was an issue that was resolved with a previous firmware update and it seems likely that you may still be on a previous version.
If you are on a previous version you can update either by connecting your phone to your PC and updating via New PC Studio or by contacting your local Customer Service team who can send the update to you Over-the-air. For more info see here.
Let me know how you get on and we'll be happy to help you further.
rosasanjuan,
Have your issues persisted after you updated your firmware? Have you spoken to Vodafone Spain at all about your issue? Let me know and I will look into the situation for you.
Thanks,
Bryan
