How often, and how, do the statistics on mailbox quotas get updated in the UI? I have a user who had an overflowing mailbox. I can either change his quota or have him delete some mail; both are reflected immediately in the status bar in the upper-right-hand corner of the Zimbra web client; however, the box still reads full (with the old quota and usage numbers) in the "Mailbox Quota" tab of the Server Statistics.

I know it'll get updated eventually. . .but what's the process/schedule for this? A "refresh" button on that tab would sure be handy. . .
