Configure the Number of Logon Failures Before Users Are Disconnected on a UM Dial Plan

  • Článek

 

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

You can specify the number of sequential unsuccessful sign-in attempts that are allowed before a caller is disconnected. The value of this setting can be from 1 through 20. Setting this value too low can frustrate users. For most organizations, this value should be set to the default of three attempts.
