Unity Server is in Domain2, users are in Domain 1. All is well until user AD accounts are migrated to Domain2. Viewmail prompts for Authentication credentials.
I've searched netpro and seen posts for this, but not one with a solution.
Here is the event log viewer.
AvCsGateway: FindCsComponents failed, no access for KT\XXXXX with subscriber type =Unknown (err=0x80070005). A subscriber must be associated with KT\XXXXX.
Elevating user to Unity admin does fix this, but obviously, cant leave them at that status.
