Outlook 2010 And Bitness


Angela’s put together a good set of guidelines for developing for Outlook 2010, particularly as it relates to whether your code is built for 32 bit or 64 bit (what we’re calling Bitness). To summarize, all MAPI or Outlook Object Model based apps and non-managed add-ins will need to be built in both 32 and 64 bit flavors to support both target environments, managed add-ins can be built as Any CPU, and VB 6 based add-ins and apps need to be scrapped and rewritten entirely. Read the full article to get the finer points, along with a good collection of links to more resources.

Enjoy!

    Steve,

    When you say VB6 apps need to be scrapped. Is this only if you want to support Office 64 bit? I thought VB 6 addins would still work with Office 32 bit?

    Thanks
