It's still one of the keys into the MAPI store, even in Exchange 2007 (the mailbox GUID is the other).

Not sure if E2k7 does anything with it or not, I would assume not since Site\Admin\Routings groups are no longer used at all in E2k7. But the main reason this is still there is for legacy client support I believe.

We ran the export yesterday and were reviewing user's info and noticed that The DN information the tool was pulling is incorrect for more than half the company. It's pointing to the old Exchange 5.5 recipients folder not to their correct OU's. We believe it's because we are in mixed mode with exchange 5.5 and the ADC is still connected. The reason we still have the 5.5 server is because the internet connector lives there. Does anyone know if we were to properly remove the ADC, would this update all their LegancyExchangeDN info to the correct information? Thanks in advance.
