If I run Outlook on Windows, the client regularly checks my quota limit and warns me when my mailbox is 90% full... giving me a chance to archive or purge stuff. This functionality doesn't seem to be present with OWA client (think MS Entourage) or ActiveSync clients (such as IOS devices or Mac Mail in 10.7 and newer. Does anyone know a workaround... maybe an Applescript or something similar that can be used from my Mac with Mac Mail setup to use Exchange to query my quota level and generate a warning (either an email or a popup, etc)?
