MS EWS Concepts

It took me quite a while to understand how Exchange works, and thus I will hereafter share the most important bits of information I have gathered concerning the concepts behind Exchange.

Folders and Items

There are 2 basic object types in an exchange store:

  • Folders
  • Items

Folders

Folders are comparable to the directories on your hard disk, in that they can contain other folders and items.

Items

Items are the actual content of the folders, you might compare them to records in a table. As with records for different tables, items do have different properties based on what type of record they contain (aka, what table they are).

Operations on Folders and Items

Creating, Updating and Deleting Items
