Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.

  1. Start Registry Editor (regedit).

  2. Locate the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<SERVER NAME>\Private-<database GUID>

  3. Do one of the following:

    1. If the OAL V4 ANR Properties DWORD exists for the subkey, change the value to the correct integral number of ULONGs.

    2. If the OAL V4 ANR Properties DWORD does not exist for the subkey, create a new DWORD with that name, and then set its value to the correct number of integral ULONGs.
