MAPI33 - a great blow to exchange development

[4096x]

Hi,

What happened to MAPI33 - I go to the website and it is gone.

This is very annoying to me as I have just finished developing a large
application using MAPI33 using the trial mapi33.dll - now I want to
purchase the full version I cannot get hold of it.

HELP!!!!!!!!

That's from MAPILab, have you contacted them about the product
(www.mapilab.com) to see if it's still available?

Hi,

I am looking a way to manage the calendars, create/cancel/delete the
meeting/appointment from the Exchange server via MAPI without installing the
Outlook.

I found that you are using the mapi33.dll libraries, and unfortunately, the
mapi33.dll is gone..

May i know is there any updated information about this libraries? I need
this libary to work out with MAPI in MS Visual Studio C#. Or is there any
other recommendation method to use MAPI without the Outlook?

Thanks for your help.

Hi,

MAPI is not supported from managed code. I wouldn't use it. If you are
working with Exchange 2000/2003, you should stick to WebDAV or CdoEx (the
latter one only works on the Exchange server itself). With Exchange 2007 you
can use the Exchange WebServices and/or the new Managed API.

Another option is Redemption (http://www.dimastr.com/redemption/) which can
be used from managed code (explicitly supported by the author).

Kind regards,
Henning Krause

Hi Chris and Henning,

Thanks for your quick response.

Chris,
Good information from the link you provided. Thanks!
One of the point that mentioned "You either need to not use .NET or not use
MAPI or CDO 1.21.".
For my case, i would definately need to use the .NET. So what is the best
way to talk to the Exchange Server 2003 in .NET environment? Is it only the
OOM? If it is, does Outlook must be installed?

I am actually looking for a way to talk (more to calendar) to the Exchange
2003 without the Outlook if it is possible.

Please advice.

Thanks,
Hua

FWIW, Matt's blog is absolutely correct about CDO 1.21 and Extended MAPI not
being supported and not really working, but almost with managed code.
However, Redemption is another story. It's specifically written as a COM
wrapper for Extended MAPI and is completely supported for use with managed
code.

I've used Redemption with managed code now for years with no problems, both
in conjunction with the Outlook object model for client side code, and as a
standalone library working with server side (Exchange) MAPI with no Outlook
installed. I've used it for Outlook COM addins, standalone Outlook related
programs and with services and console applications that talk directly to
the Exchange server with no Outlook involved.

Hi Chris and Ken,

Thanks and appreciate your help. I would be really greatful if you could
help answer my doubt below:

1) My piece of application will be deployed in Windows Server 2003, and
communicate with Exchage Server 2003. Does the Redemption support in such
environment? Should i install the Standalone version of MAPI in my Win Server
2003?

2) As mentioned in http://www.dimastr.com/redemption/download.htm, there are
two version of Redemption.
What is the difference between Developer version and Distributed version in
terms of the functionality (library) provided? Which one should i use for?
Does Developer version is enough for me if my application will be used
within only my company?

Thanks and looking forward for your clarification :)

Rgds,
Hua

1. Yes, Redemption supports an environment like that, I've used similar
setups. Redemption requires that MAPI is installed, it doesn't really care
if it's the client-side MAPI from Outlook or the server-side MAPI. Which one
you install depends on the environment and requirements. If Outlook isn't
required, or you need the ability to do things that aren't supported for
client-side MAPI then use the server-side version. In general, if you don't
need Outlook then go with server-side MAPI, it doesn't have the limitations
that the client-side version has.

2. The personal use version is just that. For your own use. The developer
version is for deployment to others. If you are developing code with
Redemption that you intend to distribute, whether commercially or within a
company, you should use the developer version. Both have about the same
functionality, although the developer version comes with other utilities and
libraries.
