I'm installing Unity 4.0(5) with Echange 2003 and with Failover. When I ran the Permission Wizard it show the next error message "The Permission Wizard has failed to set all permission for your selections. The wizard failed 1 times." The permission wizar result show that
"Deleted Objects rights: sadomoco.local/Deleted Objects
FAILED granting List contents rights
FAILED granting Read Properties rights."
in Unity Directory Service account. I have checked that account in AD and Exchange, but I have not found any problem.
Do you have any domain wide policies that is revoking these permissions ?
Have you tried re-running permission wizard to see if this clears up?
