Nokia-Outlook Sync' charset problem

[alimousios]

I have the Nokia 5800 Xpress Music phone (latest fw) and in my pc i have installed Nokia Ovi Suite 1.1, when i synchronize the contacts and calendar between my phone and my pc (MS Outlook 2003 & 2007) i face a problem with Greek characters,

my contacts and calendar items are written in greek language and the strange problem i face is that during sync all the items (contacts and calendar) that are transferred from my pc (MS Outlook 2003 & 2007) to Nokia 5800 are shown OK in my phone but all items that are transferred from Nokia 5800 to Outlook are not shown correctly, not greek chars (it looks like charset problem).

Any ideas?

one with windows XP (32bit) and Outlook 2003
and another one with Windows Vista (32bit) and Outlook 2007
