Could anyone please suggest a method to recover an accidentally deleted public folder? The retention period is 30 days for public folders and other mailbox folders. I tried to recover using outlook, but permission error happened even with administrator account. so i used pfdav admin tool and the deleted public folder was displayed in red. But recovery of this folder returned an error message. “An unexpected error occurred. Exception: The operation has timed out. I did another public folder recovery using this tool few days ago and operation was successful, but not this time. Thanks in advance.
