Set the PIN lifetime for voice mail in Exchange Server
Applies to: Exchange Server 2013, Exchange Server 2016
You can configure the PIN lifetime for users who are enabled for Unified Messaging (UM). The PIN lifetime is the maximum time that an Outlook Voice Access PIN will be valid for UM-enabled recipients. The PIN lifetime setting is configured on a UM mailbox policy and applies to all UM-enabled users associated with the UM mailbox policy.
Several PIN-related settings can be configured on a UM mailbox policy. The PIN lifetime setting controls the time interval, in days, from the date Outlook Voice Access users last changed their PIN to the date they'll be forced to change their PIN again. The range is 0 through 999, and the default is 60 days. If you enter 0, the user's PIN won't expire. We recommend that you don't configure this setting to 0, because by doing so you greatly reduce the security of your network.
Important
Unified Messaging doesn't notify users when their PIN is about to expire.
