I am looking to have my site that is running Exchange 2007 and a BES to have some users given the ability to send mail internally without their delegates (assistants) having the ability to read it. The other part that I would love to do? Have it work with their blackberry's.
So, thought I want the users to be able to send mail normally as well and have their delegates be able to see it as normal - they wish to have some messages between a few users be completely private. I am more than OK with a solution that requires a password that only the messager and messagee (not delegate) has. I am also OK with a message that can be sent only via blackberry.
If you need any more specific information, please request it. Note: Exchange 2007, Office 2007, Server 2003 R2, BES Express. Not afraid of spending money for solutions, or upgrading.
