Found this in another thread. it resolved the problem. this is associated with outlook crashing specifically after a windows update. it leave an entry in the event viewer every time outlook crashes.

If the message in event log is talking about loadperf.dll, then delete the following key to resolve.
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Outlook
Seems to have happened after an update.
