XCLN: Err Msg: Spell Check Operation could not be Completed (164156)

SUMMARY

When spell checking a message within a Microsoft Exchange Windows client, the following error may be displayed

The spelling operation could not be completed. The spelling
checker could not be started. Some components are either missing
or incorrectly configured in your Win.ini file. See your
administrator.

This error is usually due to the Microsoft Exchange Client looking for spelling files in either an invalid directory or a location that you don't have permission to access. Confirm the following registry entries and Win.ini entries point to valid files stored in accessible locations.
