|Message:||The Microsoft Exchange Unified Messaging service detected a corrupted PIN for user “%1”. The user’s UM configuration data contains information such as the user’s current PIN and the number of consecutive times the user has entered an incorrect PIN. The user will not be able to log on to the Unified Messaging system until their PIN is reset.|
This Error event indicates that the PIN file that is used to access the mailbox from the telephone is corrupted. The file is stored in the user mailbox. The file contains the user’s current and pervious PINs, the number of consecutive times the user has entered an incorrect PIN, and the time the PIN was set. The user mailbox will be unavailable from the telephone until the PIN is reset by the user or by the Exchange administrators. This event may be caused by a corruption of the mailbox. It may also be caused when a third-party software application modifies the PIN file.
