V-79-57344-4611 error

When I try to restore an exchange mailbox I get this error message. "V-79-57344-4611
 - An error occured creating or accessing the directory specified for this operation."

 

I've looked up this issue and it mentioned to redirect where I'm restoring. However this has not resolved my issue. I can restore data files, the issue comes when restoring exchange mailboxes.

 

Any help appreciated. Thanks
