This is because MAPI is 32 bit only, and explicitly unsupported when called from .NET.

It will not, ever, work in 64 bit mode.

We had to write a seperate worker app in C++ to get it stable enough for commercial use, so if you are only working with Ex2007, I strongly suggest you look t the web services, NOT MAPI - it's a dog, impossible to debug and maintain once it gets complex, and microsoft will NOT support it - even if you pay - if you are calling it from .NET.

:)

Oh yeah, you mantra: close you handles ;-) tho generally, you can't force them closed in .NET, which is part of the problem. Expect to cycle the process often :)

mate, this post saved my life!! building an app calling 3rd partie lib's on a vista 64 ult + vs 2005 and kept breaking with that error.

i had to install a virtual pc with xp and build everytime on that!

thanks heaps.

Hi,

I am trying to retreive metadata from OLE Using DSOFile.dll. Its working perfectly fine on my XP X86 Environment.
When i run the same in Windows Server x64 Environment, I am getting Error Saying "

System.Runtime.InteropServices.COMException was caught
Message=Retrieving the COM class factory for component with CLSID {58968145-CF05-4341-995F-2EE093F6ABA3} failed due to the following error: 80040154.
Source=FileShareToSP2010Accelerator.UI.ConfigControl
ErrorCode=-2147221164
StackTrace:

Code:
Installed DSOFile from the following location
http://www.microsoft.com/downloads/en/details.aspx?FamilyId=9BA6FAC6-520B-4A0A-878A-53EC8300C4C2&displaylang=en

then add the reference DSOFile.DLL to my project ,
DSOFile.OleDocumentPropertiesClass oDso = new DSOFile.OleDocumentPropertiesClass();
oDso.Open(sFileName, true, DSOFile.dsoFileOpenOptions.dsoOptionDefault);
string strAuthor = oDso.SummaryProperties.Author;

This is working fine for XP x86 and not Working for Server 2008 X64 bit envirnoment
Any Pointers on how to retreive metadata on Windows Server 2008 using DSO File Would be great help.

Thanks,
