(Tcl) Outlook -- Create Map of Folder Paths to IDs

Recursively descends folders and creates a hashtable of folder paths to IDs. This can be done once at the start of your program (or even less if the map is persisted to a file or database).

The reason this is necessary is because folder ID's need to be passed to the Outlook API, and an application will typically be working with folder paths.

Note: This example requires Chilkat v9.5.0.67 or greater.

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