I have granted VSA with the correct Permissions for Exchange Server (Full Control,Send As and Receive As) but when create a Mailbox Archiving Task and start it show the next error in the Event Viewer.

Event Type: Error
Event Source: Enterprise Vault
Event Category: Archive Task
Event ID: 3305
Date: 11/22/2006
Time: 11:17:38 AM
User: N/A
The Task 'Mailbox Archiving Task for EXCHSERV' failed to log on to Exchange server 'EXCHSERV' using mailbox 'EnterpriseVault(EXCHSERV)'. Please ensure that the server is running and that the Vault account has sufficient permissions on the server.

Exchange 2000/Win 2000
EV 6.0 SP3/Win 2003 Server ENT

SomeOne have a idea ?? Thanks for all
