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. To resolve this behavior, change the working folder that the information store uses for e-mail message conversion to point to a faster drive. To do so, follow these steps:

Start Registry Editor.
Locate and then click the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
In the right-side pane, double-click Working Directory:REG_SZ:Folder_Path.
In the String Editor box, type the path of a folder on a faster drive, and then click OK.
Close Registry Editor.
