This setting governs how often Exchange rereads logon quotas -- i.e., mailbox size quotas -- for users.
This may be a false notification, as it appears to a bug in Outlook 2010 when you’re running in Outlook Cached Mode.
Newer versions of Outlook can display the Exchange mailbox quota in the Status bar.
It's not a good idea to set this to less than 10 minutes, however, as this may cause an excessive number of Active Directory lookups (which produce their own variety of overhead). Please let others know how useful this tip is via the rating scale below.
