RESOLUTION
Reset the password in User Manager for any users experiencing this problem. This problem only occurs for users who were logged on at the time the Service Pack 3 upgrade was applied to the Exchange Server computer.
You can also edit the Constant.inc file, located in the Exchsrvr\WebData\language folder. In the line that reads “fEnablePasswordMenu = true,” change “true” to “false” to disable the error message.
