(Classic ASP) Outlook -- List Selected Fields in Messages

Demonstrates how to list the messages in a particular Outlook mailbox folder, but selects particular fields to be returned.

This uses the OData $select system query option. See OData System Query Option $select for general information.

Also see OData URL Conventions for information about $select and other query options.

Note: This example requires Chilkat v9.5.0.68 or greater.

' This example requires the Chilkat API to have been previously unlocked.

' Use your previously obtained access token here:
' See the following examples for getting an access token:
'    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
'    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
'    Refresh Access Token (Azure AD v2.0 Endpoint).
'    Refresh Access Token (Azure AD Endpoint).

' In this example, we'd like to get the messages in the folder "/Inbox",
' but we must specify the corresponding folder_id.  The best way to do this is to create
' a local map of folderPaths-to-folderIds.
' This example does it:  Create Outlook Folder Map)
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Hashtable")
