I am attempting to test a new managed folder mailbox policy that has been configured and associated with a single mailbox. When I try to run the assistant manuallly using the EMC I receive the following error: “The call to the Mailbox Assistants service on server xxxx failed. Error from RPC is 5.” This error is generated regardless of whether I try to run the service on the mailbox, server or domain. I have verified that the service is running and set to logon as local system account. Any ideas as to why the assistant will not run?
