Outlook library requires WM5.0 or WM6.0 device and .Net CF 2.0.
Until the next version, you should make sure that the config file (YourApp.config.exe) which the compiler creates is also in the same folder of the executable.
WM 5.0 and MSCF2.0 is present in the folder. Now the config file is present too.
The Error doesn't appear.
The result is a frozen Waitcurser, but the program doesn't start like the source in the Device-Editor. Do you have another advice.
