getting consolidate list of "follow up" items

[Lawrence]

Dear All,

I would like to get a consolidated list of items (sent and received
mails)that have matured - i.e. whose follow up time is up.

I have the habit of tagging a sent mail (after actually sending) for
follow up.
Similarly, mails received are also tagged for my further action (for
follow up).

Would appreciate a consolidated follow up report generation way -
rather that opening each folder and looking for mature items (i.e.
red).

Thanks in advance.

Sanjay
