Configure the Number of Incorrect PIN Entries Before a PIN Is Reset on a UM Mailbox Policy

 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Topic Last Modified: 2012-07-23

You can configure the number of logon failures allowed before the PIN is reset for an Outlook Voice Access user. You can configure the number of logon failures allowed before a PIN is reset from 1 through 998. The default is 5. The number of logon failures allowed before a PIN is reset is configured on a Unified Messaging (UM) mailbox policy and applies to all UM-enabled users associated with the UM mailbox policy.

noteNote:
You can increase security by configuring the Number of incorrect PIN entries before PIN is automatically reset setting to a number less than 5. You decrease security if you configure it to a number more than 5.
