Offline Restore Procedure for Exchange 2000 2003

Make sure that the Information Store service is stopped before you run the Eseutil.exe program that is mentioned in step 3.
Run the following commands to check the consistency of the public and private databases (these lines have been wrapped for readability).
C:\Program Files\exchsrvr\BIN>eseutil /mh
"drive:\Program Files\exchsrvr\MDBDATA\priv1.edb"
C:\Program Files\exchsrvr\BIN>eseutil /mh
"drive:\Program Files\exchsrvr\MDBDATA\pub1.edb"
To verify that the .edb file is consistent, check the output line that is labeled "State." If you want to send the output of this command directly to a text file, you can modify the command line as follows (the following lines have been wrapped for readability).
C:\Program Files\exchsrvr\BIN>eseutil /mh
C:\Program Files\exchsrvr\MDBDATA\priv1.edb > mypriv.txt
C:\Program Files\exchsrvr\BIN>eseutil /mh
C:\Program Files\exchsrvr\MDBDATA\pub1.edb > mypub.txt
If one of the databases is inconsistent, try to perform a soft recovery of the files to see if there are copies of the log files stored in the Mdbdata folder.
To initiate a soft recovery, run the following command.
Open the folder where the database and log files reside, and then type the following at a command prompt. The following line has been wrapped for readability.
C:\Program Files\exchsrvr\MDBDATA>"C:\Program Files\exchsrvr\BIN\eseutil" /r E00
Click Yes to run the repair. Performing soft recovery...
When the soft recovery is complete, the program displays the message:
Operation completed successfully in x.xxx seconds.
At the command prompt, type the following commands (the following lines have been wrapped for readability):
To bring the Priv1.edb file back into a consistent state:
C:\Program Files\exchsrvr\MDBDATA>"C:\Program Files\exchsrvr\BIN\eseutil" /p priv1.edb
To bring the Pub1.edb file back into a consistent state:
C:\Program Files\exchsrvr\MDBDATA>"C:\Program Files\exchsrvr\BIN\eseutil" /p pub1.edb
Click Yes to run the repair.
When the procedure is complete, the program displays the message:
Integrity check successful.
Note The .stm files are automatically included in the repair process.
Delete all .log files in the Mdbdata folder, delete the .chk file, and then delete the Temp.edb file (if it exists).
Mount the databases one time, and then immediately dismount them to so that users cannot access them during this procedure.
Stop the Information Store service and run a defragmentation of the private and public store databases. You must run this step if you are low on disk space. At a command prompt, type the following commands (the following lines have been wrapped for readability):
To defragment Priv1.edb:
C:\Program Files\exchsrvr\BIN>eseutil /d
C:\Program Files\exchsrvr\MDBDATA\priv1.edb
To defragment Pub1.edb:
C:\Program Files\exchsrvr\BIN>eseutil /d
C:\Program Files\exchsrvr\MDBDATA\pub1.edb
Note If both the private and the public information store databases are large, this step may take some time. If you receive an error message that indicates a lack of disk space when you try to perform this step, copy the Program Files\ExchSrvr\Bin folder to a drive that has more disk space, and then try to run the command from that location.
Use Isinteg.exe to fix the Pub1.edb database and the Priv1.edb database. The Isinteg.exe utility runs a test on all areas of each of the databases and reports the results. Isinteg.exe also tries to fix any issues that are encountered.
To fix Priv1.edb, type the following command at a command prompt (the following line has been wrapped for readability):
C:\Program Files\exchsrvr\BIN>isinteg -s (servername) -fix -test alltests
Note To obtain or confirm the server name, type the following command at a command prompt on the server:
nbtstat -n
You are prompted to select the database to be checked.
You can only check databases that are marked as offline. The Information Store service must be started, but the information store must be dismounted.
When you select a database, you are prompted with the following message to confirm the selection:
"You have selected First Storage Group / Mailbox Store <servername>
Continue? (Y/N)"
Press <B>Y</B> and <B>Enter</B> to start checking the selected database.
You receive a summary report that indicates the number of tests that were run, the number of warnings, the number of errors found, the number of fixes attempted, and the time it took for the program to run. If there are any warnings, errors, or fixes, run the command again. Repeat this step until there are no warnings, errors, or fixes reported
Now in test 3 (reference count verification)of total 3 tests;
100% complete.
Restart the information store.

ExMerge

Using the ExMerge utility
If the information store starts, but there are other issues, you can use the ExMerge utility to export all the user's mailboxes to .pst files. Then, merge the .pst files to user mailboxes to a newly created Priv1.edb file. You can also move the public folder contents in this manner.
If you use offline storage for e-mail (.ost files), you must move the .ost files to a .pst file before you start this procedure to prevent the loss of any .ost data.
Before you use the ExMerge utility, be aware that you can use ExMerge to move only user mailboxes. You cannot use ExMerge to move specific Exchange 2000 configuration properties such as connector settings, Outlook settings, or client-side rules. You also cannot use ExMerge to move distribution lists, memberships in those distribution lists, or public folders. You can move public folder contents into a user's personal folders to include the public folder information in the merged .pst file. If you try this procedure, you must re-create or reconfigure the distribution lists manually.
Note This procedure also removes the single instance store for messages that were received up to that point. As a result, the Exchange 2000 databases may grow and require more disk space.
Copy these files to the\Exchsrvr\Mdbdata\Bin folder, and then follow these steps:
Make sure that there are no users who are currently accessing e-mail or have their e-mail client programs running.
Run ExMerge by using step one of the two-step merge, and then enter all the users.
When the ExMerge process is complete, stop the Exchange 2000 Information Store service, locate and open the ExchSrvr\Mdbdata folder, and then rename the Pub1.edb and Priv1.edb files.
Delete all the other files in this folder. Make sure that you do not delete the renamed Pub1.edb and Priv1.edb files until you are sure that the merge was successful.
Restart the Exchange 2000 Information Store service.
Start Outlook on a client computer, and then send an e-mail message to all the users in the Exchange 2000 global address book.
When this process is complete, the e-mail messages that were in the .pst files are moved to Exchange 2000 mailboxes.
You have a new Priv1.edb file that contains copies of all the e-mail messages.
Re-creating the Pub1.edb database
From a client such as Outlook, copy the public folders to the user's personal folders on the client.
Stop the Information Store service, and then rename the existing Pub1.edb and Pub1.stm files.
To create the new Pub1.edb, mount the public folders database.
Click OK to create the new Pub1.edb.
Note You must reinstate any permissions on the public store.
From the client, move the folders back into the new public folder structure on the server.
Important After you can access both e-mail and public folders, perform and verify a successful backup as soon as you can.
