    is this version 8353 supported for exchange 2013 ? and version 8244 is for exchange 2010 ?

    I havent found any information for which version MAPI/CDO is for version of exchange.

    @Kamil – I would recommend you to use the latest MAPI/CDO for Exchange so that you can avoid the issues which are reported to us/fixed in the latest's ones.

    Im relieved to have found this post after 2 days of struggling with mapi. But really annoyed that searches for mapi cdo refer me to the may 2013 update rather than the most recent  (this one ). And even more bizarre that they are both v1.2.1.

    @Peter – i am glad this post helped

    The Exchange MAPI CDO 1.2.1 March update is great.  However, no place can I find if it fully supports x64 bit applications, or is it only x86 or 32 bit application capable only.  Otherwise, its time to take on EWS and drop MAPI.
