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.

# ---------------------------------------------------------------------------
# To get the number of emails in a particular folder, we need to use the folder id.
# 

# In this example, we'd like to get number of messages in the folder "/Inbox/abc",
# but we must specify the corresponding folder_id.  The best way to do this is to create
# a local map of folderPaths-to-folderIds.
# We'll use the map created by this example:  Create Outlook Folder Map)
