I had two exchange accounts to two different organizations. One did not require provisioning nor security code and that one worked fine. The one that doesnt work is unfortunately the bulk of my email, and that organization requires provisioning and security lock. I dont disagree that for many it probably works fine. However, Maemo has had issues with Mfe for a long time now, and they have not been able to take care of it for years. Hence my description of a C team at NOKIA
