SYMPTOMS

The following error may occur when you try to start the Microsoft Exchange Server Information Store service after an online restore:

   -1605 Jet_errKeyDuplicate.

CAUSE

This can occur when the RestoreInProgress key is not removed from the registry. This key is removed when the log files are replayed. If no log files have been replayed, you need to remove the key yourself.

RESOLUTION

To resolve this problem:

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

1. Remove the RestoreInProgress key from:

         HKEY_Local_Machine\System\CurrentControlSet\Services\MSExchangeIS
   

2. Restore the information store again.
