The Microsoft Exchange Mailbox Merge Program (Exmerge.exe) enables an Exchange Server administrator to extract data from mailboxes on an Exchange Server computer and then merge this data into the same mailboxes on another computer that is running Exchange Server. The Exchange Server 4.0, 5.0, and 5.5 version of this program is included in the Microsoft BackOffice Resource Kit, Second Edition. The Exchange 2000 Server version of Exmerge is included on the Exchange 2000 Server CD in the Support Tools folder.
Exmerge.exe copies data from the source server into personal folder (PST) files and then merges the data in the personal folders into the mailboxes on the destination server.
The program has two modes of operation: One Step and Two Step.
In One Step mode, the program copies data from the source mailbox to a PST file and then merge the data in the PST file into the same mailbox on the destination server. In this case, the mailbox on the destination server must have the same mailbox name and the same container path. The Distinguished Name (DN) of the mailbox on the destination server is obtained by replacing the Organization and Site names in the DN of the mailbox on the source server with the Organization and Sites names of the destination server.
In Two Step mode, the user has the option of only copying data to PST files or merging data from PST files into a server.
For this program to successfully work, the user must be logged on to Microsoft Windows NT with the Exchange Service account. If this is not possible, then the current Windows NT account must have permissions on all mailboxes selected to be merged.
The program creates a log file called C:\Exmerge.log, which contains any errors encountered during operation.
