We are using Backup Exec 9-1 and every night during the backup a certain mailbox is getting the following error... Backup - \\Server\Microsoft Exchange Mailboxes Access denied to file User Name [inbox]Top of Information StoreInboxWarning: could not send message for past 4 hours. We have moved all email into a .pst for a couple of days then imported them back in and the backup is still getting the error I have looked in the outbox and there is no email there waiting I have checked the sync issue folder and nothing there either. Any thoughts on this??
