Outlook is entirely MAPI based, it would have to be rewritten from scratch
to not use MAPI. Same for Exchange server. ECE's aren't going to be
supported for Outlook in the future, but you still will be able to write COM
addins using Extended MAPI.

Hi folks,

I am developing an outlook com addin. Because the outlook object model
is limited it resorts to extended mapi in many fields. Reading about
the latest exchange developments there is stated that Mapi32 is
deemphasized. Does that also mean that extended mapi won't work in
future versions of outlook, meaning my com addin will be useless?

Cheers,
Ron.
