My name is Ken. Thank you for using the Microsoft Access Newsgroups.

As you are aware, the implementation of the Outlook Security Update was in
response to malicious e-mail messages that were affecting Microsoft Outlook
users.

While the security updates can be somewhat of an inconvenience to the end
user and the developer who is implementing e-mail capabilities within an
application, the purpose of the update was provide additional levels of
protection against these malicious e-mail messages.

To address the questions outlined in your message.

1.  Is there a way to denote that a specific application is "trusted" and
thereby bypass the security settings of Microsoft Outlook?  

There is not a method of setting up or specifying a "trusted" program.  Any
program that is attempting to send e-mail either through Microsoft Outlook,
CDO, or through Simple MAPI will cause a warning message to be displayed to
the end user.  The user must then select whether or not to allow the
message to be sent.

2.  Is there a solution to the issue that you are encountering where you
need to send 150 e-mail messages and do not want the user to have to agree
to send all 150 e-mail messages?

Depending upon exactly how the e-mail messages are being sent or need to be
sent, you may be able to build a string of e-mail addresses and then pass
this string into the TO argument of the code that is sending the e-mail.  
This may allow you to significantly reduce the number of individual e-mail
messages that are sent and thereby reduce the number of confirmations
required by the end user.

I have included links to a couple of articles below that further address
the Outlook E-mail Security update.
