Fixing Large Kerio Mailboxes I bet you have customers who never delete anything out of their Inbox, or if they do, they never empty their deleted items folder. If they are using Outlook PST files, they will sooner or later reach the maximum file size possible and their mail will break (actually, with Outlook it will usually break before that). Sometimes you can fix it with SCANPST.EXE, sometimes you can't.
