Demonstrates search the messages in a particular Outlook mailbox folder.

This uses the OData $filter and $search system query options. See OData System Query Options for general information.

Also see OData URL Conventions for information about $filter, $search and other query options.

  • Find emails from a particular email address.
  • Find emails where the subject contains a particular word or phrase.
  • Using an "AND" expression.
  • Find emails received in the last 24 hours.
  • Find emails received in October 2016
  • Find unread emails
  • Find emails containing a particular phrase in the body.
  • Free-text search of a keyword or phrase.
  • Free-text search of an email address.
Note: This example requires Chilkat v9.5.0.68 or greater.

This example applies to: Exchange Online | Office 365 | Hotmail.com | Live.com | MSN.com | Outlook.com | Passport.com
