Hello to everyone. I have made a damage!!! Three months ago we havean Exchange 2003 SP2 server. Then we have migrate it to Exchange 2007 (transition mode). We have moved all the mailbox. Yesterday we have delete the last Exchange 2003 SP2 server from the domain (with the EX2003 Setup). After that we have many problems with Exchange 2007: -many items from Active Directory Configuration are missed: so I have copied it manually; -now the big problem is that Information Store Server doesn't start (error 7024: The Microsoft Exchange Information Store service terminated with service-specific error 0 (0x0). and error 9564: Error 0x8004010f starting the Microsoft Exchange Information Store. Failed to init VSERVER. ). I have tried to copy "Mailbox Database.edb" to another server in a demo LAN (with the same name and settings): when I mount the "Mailbox Database.edb" I receive this error:"Error code: MapiExceptionCallFailed: Unable to mount database (hr=0x80004005,ec=1276). Please help me!!! Now I have this idea: I remove the corrupted Exchange 2007 server. I will make a new installation with same names and same settings. How could I restore the "Mailbox Database.edb"? Thank you for your support!! Alessandro
