I've been tasked with modifying an outlook OTM file that currently ask the users a question when sending mail

The OTM file asks the users if they would like to send a copy of the mail there sending to a predefined mailbox (BCC)

What I need to do is change the script so it reads group membership of the user and based on the group membership gives them a drop down box. this drop down will give them a choice of mailboxes to BCC the mail to.
for example

If user A is a member of group Domain\projectA and domain\ProjectB then the dropdown would give the user the drop down box when sending a mail to choose between the projectA and Project B mailboxes for Bcc.

Is the above possible?

the current OTMfile has the below code in it.



I hope this is possible

Thanks chris
