Some MAPI Constants

[This is now documented here: https://msdn.microsoft.com/en-us/library/ff960239.aspx ]

Dmitry pointed out that some time in the last couple MAPI documentation refreshes, we added documentation for a few interfaces but forgot to define their associated guids. We’ve got a bug tracking this and plan to fix it in a future reference, but in the mean time, here are the constants we’ve identified so far as missing.

// IMAPISync
DEFINE_GUID(IID_IMAPISync, 0x5024a385, 0x2d44, 0x486a,  0x81, 0xa8, 0x8f, 0xe, 0xcb, 0x60, 0x71, 0xdd);

// IMAPISyncProgressCallback
DEFINE_GUID(IID_IMAPISyncProgressCallback, 0x5024a386, 0x2d44, 0x486a,  0x81, 0xa8, 0x8f, 0xe, 0xcb, 0x60, 0x71, 0xdd);

// IMAPISecureMessage
DEFINE_GUID(IID_IMAPISecureMessage, 0x253cc320, 0xeab6, 0x11d0, 0x82, 0x22, 0, 0x60, 0x97, 0x93, 0x87, 0xea);

// IMAPIGetSession
DEFINE_GUID(IID_IMAPIGetSession, 0x614ab435, 0x491d, 0x4f5b, 0xa8, 0xb4, 0x60, 0xeb, 0x3, 0x10, 0x30, 0xc6);

Please let me know if you uncover any other constants which we left out.

Enjoy!
