GMT compatibility and the E71 in Israel

Question

I am using the E71 in Isreal, now it is winter time GMT+2
but when I receive an invitation for a meeting using my Mail For Exchange application and confirm it from the Nokia, it is inserted to the calender 1 hour earlier !
For instance, if I received an invittion for a meeting at 10:00 it ends up in my calendar at 09:00 !
However, if I open the invitation and confirm it from my outlook - than sync the Nokia there is NO problem !
The Exchange server is also GMT+2 Jerusalem time.
Local support in Israel (Orange) said to try and set the time zone to another country - but the problem is NOT solved.
I had a similar problem during Summer time (we changed October 5th) when it was GMT+3, and I solved it at the time by setting the time of the phone to Nairobi - Kenya time which was also GMT+3.
Any help will be highly appreciated.

Answer 1

Thanks for the quick response, however, it does NOT help.
It solves only part of the problem, if I for instance insert a meeting in my Nokia, it will be done at the same hour at the exchange, however, when I open and confirm a meeting in the Nokia, a meeting request sent by another person - it will be inserted one hopur eearlier into the exchange.
As I wrote before, if I confirm the meeting from the Oulook first, it wil be snced properly into the Nokia.
By the way, my MFE version is 2.05 and I see there is a newer version 2.7 Is this something I should consider updateding / upgrading ?
Thanks,
