Resolution

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

  1. Start Windows NT Registry Editor (Regedt32.exe), and locate the following registry key:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet
  2. On the Security menu, click Permissions.
  3. Click to select the Replace Permission On Existing Subkeys check box.
  4. In the Name box, click System, and then click Full Control in the Type Of Access box.
  5. In the Name box, click the Exchange Service Account, and then click Full Control in the Type Of Access box.
  6. Click OK, and then quit Registry Editor.
