In the exmerge log it says that I dont have permission to open the store.
I am logged in as admin.
Here is the kicker... I go to exchange system manager. then browse to the mailbox store and right click. Go to properties and security. Domain admins has both allow and deny but and grayed out on send as and recieve as.
When I add the administrators group to the list to give full controll it also grays out recieve as and send as.
