I am trying to access (download) volumes of emails from Exchange server periodically. EWS won't be a choice because the concern of performance due to the amount of data.
MAPI seems to be the choice for this task. But I am having some difficulties to find the code example with some good documentations. Also with MAPI Reference page, I am not sure if I find the correct place.
This seems to be under the context of outlook. I don't need to go through Outlook. I need to access Exchange server directly.
Your help is highly appreciated. Thx.
