Mapping Exchange fields to non-default AD attributes

[outlook]

I know you can customize the display templates in Exchange. What I am thinking of is a little different. Basically I want to abstract the Exchange fields from the concrete implementation of specific AD attributes.

For example, I want to be able to tell Exchange to look for its Title value in the AD attribute of foo-title (let's say a custom schema extension we've done). So then whereever Exchange uses its Title, it will be getting and setting the foo-title attribute. Title -> foo-title instead of Title -> title or Office -> foo-office instead of office.

The reason why just changing the display templates would not work is because I'd still want to use my powershell commands. So if I was creating a dynamic distribution list, and passed in the OPATH filter of -Title, I would want the powerscript shell and distribution list to be reading from the foo-title.

TIA
