Reset a voice mail PIN in Exchange Server
Applies to: Exchange Server 2013, Exchange Server 2016
When a Unified Messaging (UM)-enabled voice mail user is locked out of their mailbox using Outlook Voice Access because they tried to sign in using an incorrect PIN multiple times or they forgot their PIN, you can use one of the following procedures to reset the user's PIN. When you reset a user's Outlook Voice Access PIN, you can configure UM to automatically generate a PIN or you can manually specify the PIN. The new PIN is sent to the user in email. You can specify additional PIN options such as requiring the user to reset their PIN when they first sign in. Users can also reset their UM PIN using Outlook or Outlook Web App.
Note
To access their UM-enabled mailboxes, Outlook Voice Access users need to use touchtone, also known as dual tone multi-frequency (DTMF), inputs. Speech recognition isn't available for PIN input.
For additional tasks related to Outlook Voice Access PIN security, see PIN security procedures.

Use the EAC to reset a Unified Messaging PIN
In the EAC, navigate to Recipients. In the list view, select the user mailbox that you want to view.
In the details pane, under Phone and Voice Features, under Unified Messaging, click View details.
On the UM Mailbox page, under UM mailbox settings, click Reset PIN.
On the Reset UM Mailbox PIN page, use the following options to reset the UM-enabled user's PIN:
Automatically generate a PIN: Use this option to automatically generate the PIN that's used by the user to gain access to their mailbox using Outlook Voice Access. By default, this setting is enabled.
The automatically generated PIN will be sent in an email message to the user's mailbox. After they receive the PIN and sign in to their mailbox, they'll be prompted to change the PIN to a PIN that's more familiar to them.
Outlook Web App and Microsoft Outlook also let the user reset their PIN. The PIN is automatically generated based on the PIN policies that are configured on the UM mailbox policy that's associated with the user's mailbox. We recommend that you automatically generate PINs for Outlook Voice Access users.
Type a PIN: Use this option to manually specify a PIN for an Outlook Voice Access user. By default, this setting is disabled.
If you specify a PIN for a user, the PIN will be sent in an email message to the user's mailbox. After they receive the PIN and sign in to their mailbox, they can change the PIN by configuring personal options in Outlook Voice Access. However, in Outlook Web App and Microsoft Outlook, there is no option to manually specify a PIN.
Require the user to reset their PIN the first time they sign in: Use this option to require the user to reset their PIN when they first sign in to Outlook Voice Access. By default, this option is enabled.
If you select the option to automatically generate a PIN for a user, you can enable this option to require users to change their PIN when they first sign in to Outlook Voice Access. This helps protect the user's PIN.
Click Save.
