Because that example was simplistic in nature, we
will build off of it and describe some of the other parameters that you can use to provide customization
to UM users.
Any configuration changes that are issued with the Set-UMMailboxPolicy cmdlet require that the
Identity parameter be specified. Although the Identity parameter is positional and providing the
value is sufficient, while getting used to PowerShell it is recommended to include it.
The first modifiable option is to allow common patterns ( AllowCommonPatterns ) within the PIN. This
parameter allows for a tradeoff between ease of use for the end user and a best practice for the security
of passwords. When modifying this parameter a thorough analysis of your company ??™ s security policies

should be performed to keep the users ??™ PINs acceptable within your security policy. Remember, the PIN
is a password to the voice mail of a user. If someone guesses a trivial PIN for a member of executive
management or another employee with access to sensitive information, he would be able to read and
respond to that user ??™ s email, voice mail, and calendar. Consider the ramifications of this setting before
actually setting it.
Access to dialing another user ??™ s extension or to dial outside the country can be controlled on a
user - by - user basis also.
