Hello,I reinstalled my Exchange 2007 server and replayed the logfiles so my edb file is rebuilt again in another folder. What is the best procedure to mount this edb-file and afterwards extract a mailbox from it? I tried to overwrite the "Mailbox Database.edb" that was created when I was reinstalling Exchange, but then I get the error 1276 database does not match the DN of directory when I try to mount it. The server is installed outside the directory as a virtual server. Is there a way to pount that database on the new virtual server?Thanks

Hi,See a solution from microsoft here http://support.microsoft.com/kb/264437regards from www.windowsadmin.infoManuPhilip

Hi,Please verify if the Organization name is the same as the previous one.If not,please uninstall the Exchange and then re-install with the right Orgniazation name.Regards,Xiu

Thanks Xiu Zhang,That solved it. In fact the error exactly what it should be, but I was always looking over it. Just one more question: If you rebuild a database until a certain date, then what about the messages that have been downloaded with pop3? Will they be available for download again?Thanks

Hi, Exchange 2007 used the Article ID (PR_INTERNET_ARTICLE_NUMBER, ptagFolderInternetId,ptagImapUID) return as the UID for the UIDL command. This value changes with any modification to the message, including setting a flag. The Outlook clients stores a list of the UID values locally for each message that it downloads, and uses these to confirm that it is not downloading duplicate messages I have set up a lab, using recovery storage group to recover mailbox and then check the value on PR_INTERNET_ARTICLE_NUMBER via MFCmapi and found that the value has been changed after the message recovered from backup. Thus I think the message will be downloaded again after you recover the mailbox. Also I recommend you test the issue in your lab to verify if the value on PR_INTERNET_ARTICLE_NUMBER will be changed. Regards, Xiu

Hello Xiu,Thank you very very much!!! I will verify it in my testlab, but at least now I am sure that it is worth the effort. You really helped me out on this one!!!
