CAUSE
This behavior can occur because the Buffer Threshold Low Percent value is missing from the following registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem RESOLUTIONWARNING: 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, you must add the missing DWORD value in the following registry location:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem - Start the registry editor (Regedit.exe).
- Open the following subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem - Add the DWORD value: Buffer Threshold Low Percent.
- Add a hexadecimal value of 3.
