fix exchange module batch builds

This patch resolves issues building the exchange module for 32-bit and 64-bit builds using the project batch build scripts. 64-bit builds now also include dummy functions that will raise a NotImplementedError for all of the unsupported 32-bit ExchangeSDK functions.

This patch also reverts some changes to setup.py introduced in [#124] that are no longer used.

Thanks to Mark for all of his help and suggestions to create this patch.

Building the exchange module requires installation of the Microsoft Exchange 2003 SDK

Original Ticket: pywin32/patches/144

Sadly I can't make this work. I installed the new SDK and while 32bit builds work, the 64bit builds fail with unresolved externals for the UUIDs:

Creating library build\temp.win-amd64-2.7\Release\com/win32comext/mapi/src\exchange.lib and objec

Note that setup.py includes the block:

    if distutils.util.get_platform() == 'win-amd64':
        # Additional utility functions are only available for 32-bit builds.
        pass
    else:
        libs += " version user32 advapi32 Ex2KSdk sadapi netapi32"

but it's not clear there are 64bit libs in that sdk. I'm out of time to dig further. I've attached the patch rebased against current tip.

I seemed to have been behind for some reason when I cloned, so I had to manually resolve the patch. Of course I didn't realize until much later that I was simply missing [#158]. However, I don't think that should have affected my build result being different.

That said, I also originally failed building. Except I failed on the exchdapi module instead. The only change I needed to make for a successful build was:

diff --git a/setup.py b/setup.py
--- a/setup.py
+++ b/setup.py

         # Exclude exchange 32-bit utility libraries from 64-bit

-        if self.plat_name == 'win-amd64' and ext.name in ['exchdapi', 'exchange']:
+        if self.plat_name == 'win-amd64' and ext.name in ['exchdapi']:

             return "Haven't worked out how to make exchange modules build on vs2015"

The fact that you are able to build the 32-bit version and only failing on the 64-bit exchange module leaves me puzzled as well.

The only downloadable SDK I could find is from 2007 and requires an active subscription: https://my.visualstudio.com/Downloads?q=exchange%20sdk (check the box "All downloads")
Are we sure we still want to try and attempt restoring supporting for this ?
Read #2374 (comment) for more details

[nczeczulin]

There is no 64bit lib. Also, there is an old recommendation from support against using it: EDK Library == Badness

#1404 resolved any dependency the mapi module had on it as well.

Closed by #1404 and #2374 .
MAPI modules also seem deprecated as per #2368
