MAPICDO March 2014 Release

It’s time for what is most likely the last release of the MAPICDO download. Here are the release notes:

Installation details:

  • The version given on the Download Center is 08.03.08353. The version stamped on the files, however, is 6.5.8353.0. All of the files in the update are dated January 13th, 2014.
  • If you already have a version of the MAPI Download installed, you must uninstall it before installing the new version. The installer does not upgrade, nor does it warn you if you try to install it without uninstalling the previous version.


  • We fixed a connection leak on network errors which contributed to MAPI clients getting shut out of talking to the Exchange server. More details on this fix are given here:
  • That’s it – again – this is probably the last release we’ll do to MAPICDO. If you haven’t already, move your apps to EWS, or Apps for Office, or the brand new Office 365 APIs.
