Exchange 2013 Compatible MAPICDO

As several of you have noted, we recently released an update for the MAPICDO package. This is the update you have all been waiting for, as it is now possible to build an RPC/HTTP enabled profile to connect to Exchange 2013. What several of you have also noticed is that this update did NOT come with any guidance for HOW to build such a profile. Such guidance does exist, but hasn’t been published yet. I had delayed commenting on this new package until the guidance was ready, but it’s taking longer than I thought it would.

I’m working with the team responsible for publishing the guidance to get it out the door. We’ve almost got it ready, so I expect to see it up on the download site (or the Exchange blog) any day now. Once that guidance is published, Dave will most likely publish an updated version of his How to Build a Profile For MFCMAPI guidance. I’ll link to both as soon as they’re public.

  1. In theory, it seems like this version of MAPI could allow a legacy app to connect to Office 365.  Any reason why this might not work ?

  2. Hypothetically speaking, should this MAPICDO package work with Office 365 ?

    Second comment — first one did no appear even after several hours.

    Since MS Exchange Server comes only in 64-bit version, since MS Exchange Server 2007, are there any plans to release a 64-bit version of MAPICDO package, or to include a 64-bit versions of MAPI dlls?

    Thank you,


  4. Dan – your logic is flawed. The server is 64 bit, but clients do not need to be 64 bit. There are no plans nor need to release a 64 bit MAPICDO package.

    upon "What several of you have also noticed is that this update did NOT come with any guidance for HOW to build such a profile. Such guidance does exist, but hasn’t been published yet…'

    Any news upon this?

    Because without creating profiles new MAPICDO isn't very usable… 🙂



  6. Understood – we're still working on it.

    Hi Stephen, I have posted an update after your response from Mar 25 2013, 6:46 am, but I do not see it here;

    My response was something along the lines:

    I might have not made myself clear; I know that MAPICDO package is to be used by client applications, that do not need to be 64 bit, as the server.

    However, on a resource intensive application, it makes sense to build a 64 bit client and overcome the limitations posed by the 32-bit architecture. Now, you've made it clear that, I would say unfortunately, there are no plans to ship 64-bit MAPICDO packages.

    On the other side, MS Outlook 2010 (and possible subsequent versions), comes with 64 bit supporting MAPI dll, as far as I know.

    Is it possible/supported to install such a version of MS Outlook on an Exchange Server (that has Client Access server role at least, but it could have all roles in a standalone deployment), and have a client application use that 64 bit MAPI coming with Outlook?

    Thank you,


  8. Thomas says:

    Stephen, thanks so far…

    1. Is there maybe some info/support within new MFCMAPI?

    2. upon what Vern already asked 3 weeks before (without any answer yet):

      Is new MAPICDO-package able to work with Office 365 ?

    3. Is new MAPICDO-package able to create Unicode-PSTs ?



  9. Dan says:

    This may be a bit off-topic but, with your experience in programming MAPI for Exchange Servers, what is the best solution (performance and stability wise) to develop an application to export data, at item level, from Exchange mailboxes?

    I would really appreciate your answer.

    Best regards,


  10. Dan – for new development you should use Exchange Web Services (EWS).


    1 – MFCMAPI can be used to create profiles for 2013, but you'll need details on the new props you have to set in the profile

    2 – Don't know why it shouldn't work.

    3 – No.

  11. Dan says:


    I still have one question, regarding your recommendation to use EWS for new development: I have read some posts where people were saying that applications using EWS were much slower that using MAPI. For applications dealing with large Exchange databases, where performance is crucial, can you comment on EWS vs MAPI please?

    Thank you for all your info and help,


  12. It is possible to write slow EWS applications, especially if you're not carefully optimizing your requests to only get the information you absolutely need, and to not request information you already have.

  13. Dan says:

    That response of yours is very political :-).

    Of course you can write slow EWS applications, but so you can with MAPI; however, assuming a well written application is implemented with EWS, how would perform to extract, let's say, individual mailboxes, vs a well written application using MAPI?

    Thank you,


  14. Alexander says:

    Do we have any news about guidance for HOW to build profile for Ex2013?

    We still waiting.

    Thank You

  15. pcunite says:

    I look forward to reading about how to create RPC/HTTP enabled profiles for Exchange 2013.

  16. EinmalIM says:

    Hi Steve, do you have any updates when the documentation how to connect MAPICDO to Exchange 2013 will be available?

    Thank you


  17. Paul Williams says:

    I am also interested in when the guidance for the MAPICDO profiles will be made available as this may be critical for some application migration to E2013.

    Hello Stephen,

    we have EXACTLY same problem as other guy Valery wrote yesterday in your other blog-section (and not yet responded):

    March 2013 Second Release of MFCMAPI and MrMAPI

    with last MAPICDO ( and using last MFCMAPI ( we can create MAPI profile for Exchange 2013.

    But there is a problem with Public Folders – when we logon with created profile and then try to open Public Folders store -> we get MAPI_E_FAILONEPROVIDER on Function: CallOpenMsgStore File: MainDlg.cpp Line: 436

    And then (when cursor is set on Public Folders store) it shows properties PR_RECORD_KEY, PR_PROVIDER_UID and PR_SERVICE_UID as PT_ERROR

    Can you explain how to resolve this problem?

    Any idea?

    -> seems to be bug of MFCMAPI?



  19. EinmalIM says:

    Hi Thomas,

    can you share information on how you created the profile with MAPICDO to access Exchange 2013?

    Is there already some documentation online?



  20. Valery says:

    EinmalIM – to have possibility to create MAPI profile with MFCMAPI we had to restart server after installation MAPICDO (BTW for some reason the real version of MAPICDO DLLs are 6.5.8309.0).

    And then standard way – Profile -> Advanced profile -> Launch profile wizard… -> it shows Service: MSEMS and Flag: 2 -> just click OK -> Microsoft Outlook Setup Wizard is started -> select first radio-button 'Use the following information services' (without restarting the 1st radio-button was disabled and if we selected 2nd -> it showed error on some step) -> and then pass through the wizard -> on the finish MAPI profile was created and we can access the selected mailbox. But problem with Public Folders is not resolved until now…

  21. SteveT says:

    I'd like to second EinmallM's comment, is there any documentation or a walk through of creating a basic profile that connects to Exchange 2013?

    We have an application that does not work against mailboxes that have been moved to Exchange 2013 and we believe if we can create the correct MAPI profile we'll be OK.



  22. Thomas says:


    we and also other guy reported this problem already 1 week ago:

    With last MAPICDO ( and last MFCMAPI ( it is NOT possible to access Public Folders of Exchange 2013

    Logging on via MFCMAPI and trying to open Public Folders store causes:

    MAPI_E_FAILONEPROVIDER on Function: CallOpenMsgStore File: MainDlg.cpp Line: 436

    And then (when cursor is set on Public Folders store) it shows properties PR_RECORD_KEY, PR_PROVIDER_UID and PR_SERVICE_UID as PT_ERROR

    Doing exactly the same via Outlook or OWA (both without any MAPICDO) -> all ok

    Any idea?

    This problems seems to be real MAPICDO-Showstopper for PublicFolders



  23. EinmalIM says:

    Hi Valery,

    tried that, but that gives me an error dialog "The name could not be resolved. Network problems are preventing connection to the Microsoft Exchange Server computer…".

    I think that is expected as I cannot set any RPC over HTTP options in the profile wizard of ExchangeMAPICDO. So I guess MAPI tries to directly speak RPC with the Exchange Server.

    What am I missing that you logon to the mailbox succeeds?



  24. Thomas Guttesen says:

    Any news on creating a basic MAPI profile for Exchange 2013?



  25. EinmalIM says:

    "…so I expect to see it up on the download site (or the Exchange blog) any day now…"

    Almost 2 months seem quite a while for "any day now…".

    Please, our customers ask for Exchange 2013 support of our MAPI based product.

  26. Can we get any confirmation that this even works?



  27. EinmalIM says:

    @Claus: I guess it does. At least for BlackBerry Servers there is a documentation how to configure their Server with the latest ExchangeMAPICDO package using RPC over HTTP:…/

    Maybe any BlackBerry admin who has this up an running could share information about the profile details in the registry?

    This would be the starting Point to search for a BESAdmin profile: HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWindows Messaging SubsystemProfiles


  28. KJ says:

    Still no docs on how to create a profile for Exchange 2013 (RPC over HTTP) ? – it's been over 2 months now folks …

    .. Ken

  29. RJP says:

    The delay in releasing this documentation is causing problems for us. We could get it working with a bit of trial and error, but would rather have definitive documentation to ensure that we get it right.

  30. I also need the doco on how to create an exchange 2013 profile for RPC over Http.

    This is really urgent for sites that are now using exchange 2013.
