The MAPI call 'OpenMsgStore' failed

Hej Jeg har oprettet en recovery storage group og vil restore en enkelt postkasse. men får flg. fejl. eventsfejl 9175, 9167 og 1041.
Jeg har søgt og har forsøgt at give rettighederne til det, men det virker bare stadig ikke. Er der nogen som ved hvad der skal gøres ???
