(DataFlex) IMAP Get Quota

Sends the GETQUOTA command to the IMAP server to get the quota information for a given quota root.

The GetQuota 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. The GetQuotaRoot method can be called to get the quota root for a given mailbox.
