I'm trying to figure out how to get the ToDo list filtered for just one account? I've tried customizing the view, and using the advanced filter to get just one Oulook Data file, but once I do that the filter goes bonkers and I get all sorts of results! I know it's a combination of email flags and true tasks, and tried combining filters to pull those conditions together, and simply can't get it to cooperate.

Before 2010, when the only way to get multiple mailboxes was to add additional mailboxes to the primary account, the task list pulled from just the primary account - but of course, the secondary accounts are not cached and available offline.
