I've not been able to backup the brick level of my public folders. The mailboxes work great but with Public Folders I get "E8602 Failed to read from database. (DBNAME=\\servername:\Public Folders\Other Calendars\foldername, EC=servername:Backup Agent Error -- (366) "Failed to open a folder".) \Public Folders.
I have rechecked and the backup account has Owner privalages on all the Public Folders, and sub-dirs. Any ideas?
