(VBScript) IMAP Get Quota Root

Sends the GETQUOTAROOT command to the IMAP server to get the quota root for a given mailbox. This also provides quota information for the given mailbox.

The GetQuotaRoot method is available in Chilkat starting at v9.5.0.58, and is only available for IMAP servers that support the QUOTA extension.

The information is returned in JSON format. This example demonstrates how to parse the JSON to get the desired information.

Typically, the quota root for the Inbox is the empty string.
