Remarks
The MailboxCollection.BeginRefresh method begins to asynchronously refresh the list of mailboxes represented by this collection. This could be either the list of top-level mailboxes or a set of child mailboxes. Upon completion, the Imap.EndMailboxRefresh event will be raised.
If the contents of the MailboxCollection are modified by using the methods of the MailboxCollection the collection will be automatically refreshed. MailboxCollection.BeginRefresh would typically only be used to refresh the collection if two users are using the same mail account simultaneously.
