This code scans a database for a particular mailbox, saves its GUID in a variable, and then removes the contents using the Remove-Mailbox cmdlet.

To avoid problems and to make sure that mailboxes are kept as long as they are required, many companies have adopted a simple process where they do the following: Bar Code Generator In .NET Using Barcode maker for Reporting Service Control to generate, create barcode image in Reporting Service applications. www.OnBarcode.comANSI/AIM Code 39 Generator In None Using Barcode drawer for Font Control to generate, create Code 3/9 image in Font applications. www.OnBarcode.com1.

4. Set up a suitable autoreply message for the mailbox so that anyone who sends to
the new SMTP address is told that their message won t be read .
5. Keep the mailbox online and accessible for up to 90 days .
Between 45 and 60 days is usually sufficient to establish whether the mailbox contents are required . When the mailbox is no longer required, you can safely eliminate both the account and mailbox . Email address policies
Email address policies define the format of email addresses that Exchange creates for mailenabled objects. The combination of email address policies and the cmdlets that maintain and apply the policies replace the processing performed by the recipient policies and the Recipient Update Service (RUS) in Exchange Server 2000 and Exchange Server 2003. Unlike in earlier versions of Exchange, email address policies are applied in a consistent and immediate manner because EMC and the underlying EMS cmdlets that create or update mailenabled recipients call a common set of business logic. The only way to stop Exchange from applying an email address policy to an object is to explicitly exclude it from these updates. For example: Set-Mailbox Identity 'David Pelton' EmailAddressPolicyEnabled $False
Typically, the effect of an email address policy is felt when a new mail-enabled object is created or updated or after an administrator makes a change to a policy that creates a new email address type or format. After you install Exchange for the first time, you will find that the installation has created a policy called default policy under the Hub Transport section of the Organization configuration. This policy creates email addresses using the alias assigned to the object plus the SMTP domain of the Exchange organization, and is applied to every mail-enabled object until another email address policy with a higher priority is created. For example, an object with an alias of TR in the organization contoso.com will receive an SMTP address of TR@contoso.com . Behind the scenes, each email address policy uses a recipient filter to determine the objects that come within the scope of the policy. Logically, the default email address policy must have a very broad recipient filter because it has to apply to any object for which Exchange can find no other matching email address policy. The recipient filter for the default email address policy is very simple, because the filter catches everything. You can see details of the policy with the Get-EmailAddressPolicy cmdlet: 6
Email address policies
Get-EmailAddressPolicy Identity 'Default Policy' | Select Name, *Filter*, *Exch* Name RecipientFilter LdapRecipientFilter LastUpdatedRecipientFilter RecipientFilterApplied RecipientFilterType ExchangeVersion : : : : : : : Default Policy Alias -ne $null (mailNickname=*) Alias -ne $null True Precanned 0.1 (8.0.535.0) The recipient filter ensures a match against all recipients that have an alias. It uses a filter that is preset within Exchange rather than a custom-coded filter that is designed to select a specific group of recipients. We discuss the topic of precanned and custom filters later on when we consider how they underpin dynamic distribution groups (see the section OPATH queries later in this chapter). The Lightweight Directory Access Protocol (LDAP) version of the filter is present to allow the RUS running on Exchange 2003 servers to understand the policy and use it to stamp correct email addresses on objects created on those servers. However, the ExchangeVersion only allows Exchange 2007 servers or later to manage the policy. Legacy email address policies that were created with Exchange 2003 only include LDAPbased filters and do not have the recipient filters used by Exchange 2007 and Exchange 2010. You can locate these policies as follows, to look for any email address policy that has an Exchange version corresponding to Exchange 2003. Get-EmailAddressPolicy | Where {$_.ExchangeVersion Like '*6.5*'} | Select Name, *Filter*
