Hi, I have Exchange 5.0's damaged Information Store at hands. I am desparete to extract the mailboxes data from it to pst files. I am logging as the service account and when I run EXMERGE (2 step), I get the follwoing errors: ERROR OPENING MESSAGE STORE (EMS). Varify, you have correct permissions to log on. - Unknown Error ( (CMapiSession::GetMailBoxesOnServer)) Error encountered reading list of recipients on server "CPQ01". Make sure you have Admin Permission on the Private Information Store Object. Please refer to 'f:\Exmerge\Exmerge.log' log for more information. I have searched MS web site, but there is nothing, which I can get help from. Please!!!!!
