No, only flagged items in your default e-mail storage will be shown in the
To-Do Bar in Outlook 2007. If you use a mailbox on the Exchange server, items
you flag in added PSTs will not be shown.
I use a local PST to deliver e-mails thus any flagged item within this PST
shows up in the To-Do bar, but not any item from another PSTs (e.g., Archive).
