I'm trying to restore a deleted public folder. The backup of the data was successful. When I try to restore I continue to get an "Access Denied" error. I have checked the account and it does have full administrative rights to the Exchange server and the information store. (the Resource Credential tests are successful inside BE) When I take the store offline before I perform the restore then the restore fails because it cannot connect to the resource. If I leave the store online when I do the restore job I get the access denied error. I have checked the "Allow this database to be overwritten by a restore" box inside the store's properties. I cannot do a redirect because I have only one Exchange server. Is it even possible to restore only one public folder into the store?
Yes you have to go back to the full backup, you can't only use a Differential/Incremental backup. If you restore only a differential you will see the restored file but it will not contail the data you need.
