How can I find out the size of my rules? Is a rule that moves mail from
multiple people to one location bigger than multiple rules for individuals to
one location?
According to the article, Outlook 2007 is an exception: "The rules size limit
for mailboxes in Microsoft Exchange Server 2007 has been increased to a
default size of 64 KB per mailbox. The rule limit is now a customizable limit
up to 256 KB per mailbox."
