yes. i have enabled ports ( 80 and 443 ) + ssl and clear login, but i'm getting always the same Exchange server Error.

On n95 works perfectly.

It's strange because on my administration interface i see:

Device: SmartPhone (UQExchange/1.0)
ID Device: my_id
Status: ok
Protocol version: 2.5

So the communication is ok because the server recognize the device...
