I'm running Exchange 2007. I need to grant a service account author rights to the tasks folder for all mailboxes on my server. It appears that I can do this via PFDAVADMIN using the custom bulk operations feature. I can see how to define all mailboxes, and how to specify the permission I want to apply, but how do I specify the "Tasks" Folder so the permission is applied just to it and not to the entire mailbox? I assume it's an LDAP query in the "Overall Filter" field in the Custom Bulk Operations window. Can someone tell me what that query might be, or if I'm wrong here, the steps or a link to a document instructing me how to give a single account Author rights to the tasks folder for all mailboxes on my Server?
