The "object model guard" feature of the patch imposes two extreme
restrictions on automating Outlook from add-ins that use either the Outlook
object model or Simple MAPI:

a.. If an add-in tries to send an Outlook message, the user gets a
notification pop-up and must explicitly authorize or deny each attempt to
send. The user must wait 5 seconds before the Yes button becomes available
to click.
b.. If an add-in tries to access address information in an Outlook item or
the address book or to save an Outlook item as a file, the user gets a
notification pop-up and can deny access, authorize a one-time access or
extend access for a period of several minutes. PDA sync utilities are an
example of the kind of application that will be affected by this
restriction.
The object model guard applies even if your code is digitally signed or
running from a published Outlook form. The only way to turn it off is via
the administrative options. Because of these restrictions, some Outlook
features become virtually unusable, because of the number of times the user
has to confirm the dialog boxes:

a.. Sequential routing from Word
b.. Mail merge to e-mail in Word
c.. Automated mailing programs that use the Outlook Send method
