I am using Windows 7 64 bit.
When I installed TheBat! 4.2.36.4 and configured MAPI account, then TheBat! didn't want to initialize mapi32.dll library. I took this DLL from my friend's machine (Win7 x64 too, his MAPI account works OK) and replaced my mapi32.all with his DLL, but it was resultless. Then I downloaded and installed "Messaging API and Collaboration Data Objects 1.2.1 v.6.5.8190.0", and MAPI account began working.
What is the most interesting in this story, when after all that I once again replaced my mapi32.dll with friend's mapi32.dll, TheBat! continued working!
