(Unicode C) Outlook -- Get Number of Emails

Gets the number of emails in an Outlook folder. This uses the OData $count system query option. See OData System Query Option $count for general information.

This example first gets the combined total number of messages across all folders.

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
