If you install Outlook, you then you can use all of outlook in ms-access.

For a list of built in functions. while in the code editor simply hit help,
and choose the Contents tab.
In there all things are grouped by Functions, Methods, Keywords.
If you click on the little + sign, then you can expand any of the above

If you click on the 2nd tab (answer wizard), then you can search on the ADO

library you are trying to use.
