Get-UMMailbox

The Anr parameter specifies a string on which to perform an ambiguous name resolution (ANR) search. You can specify a partial string and search for objects with an attribute that matches that string. The default attributes searched are:

• CommonName (CN)
• DisplayName
• FirstName
• LastName
• Alias

The Credential parameter specifies the username and password that's used to run this command. Typically, you use this parameter in scripts or when you need to provide different credentials that have the required permissions.

A value for this parameter requires the Get-Credential cmdlet. To pause this command and receive a prompt for credentials, use the value (Get-Credential). Or, before you run this command, store the credentials in a variable (for example, $cred = Get-Credential) and then use the variable name ($cred) for this parameter. For more information, see Get-Credential.

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

The Filter parameter uses OPATH syntax to filter the results by the specified properties and values. The search criteria uses the syntax "Property -ComparisonOperator 'Value'".

• Enclose the whole OPATH filter in double quotation marks " ". If the filter contains system values (for example, $true, $false, or $null), use single quotation marks ' ' instead. Although this parameter is a string (not a system block), you can also use braces { }, but only if the filter doesn't contain variables.
• Property is a filterable property. For more information about the filterable properties, see Filterable properties for the Filter parameter.
• ComparisonOperator is an OPATH comparison operator (for example -eq for equals and -like for string comparison). For more information about comparison operators, see about_Comparison_Operators.
• Value is the property value to search for. Enclose text values and variables in single quotation marks ('Value' or '$Variable'). If a variable value contains single quotation marks, you need to identify (escape) the single quotation marks to expand the variable correctly. For example, instead of '$User', use '$($User -Replace "'","''")'. Don't enclose integers or system values in quotation marks (for example, use 500, $true, $false, or $null instead).

You can chain multiple search criteria together using the logical operators -and and -or. For example, "Criteria1 -and Criteria2" or "(Criteria1 -and Criteria2) -or Criteria3".

For detailed information about OPATH filters in Exchange, see Additional OPATH syntax information.

The Identity parameter specifies the UM-enabled mailbox that you want to view. You can use any value that uniquely identifies the mailbox. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Domain\Username
• Email address
• GUID
• LegacyExchangeDN
• SamAccountName
• User ID or user principal name (UPN)

The IgnoreDefaultScope switch tells the command to ignore the default recipient scope setting for the Exchange PowerShell session, and to use the entire forest as the scope. You don't need to specify a value with this switch.

This switch enables the command to access Active Directory objects that aren't currently available in the default scope, but also introduces the following restrictions:

• You can't use the DomainController parameter. The command uses an appropriate global catalog server automatically.
• You can only use the DN for the Identity parameter. Other forms of identification, such as alias or GUID, aren't accepted.

The OrganizationalUnit parameter filters the results based on the object's location in Active Directory. Only objects that exist in the specified location are returned. Valid input for this parameter is an organizational unit (OU) or domain that's returned by the Get-OrganizationalUnit cmdlet. You can use any value that uniquely identifies the OU or domain. For example:

• Name
• Canonical name
• Distinguished name (DN)
• GUID

The ReadFromDomainController switch specifies that information should be read from a domain controller in the user's domain. You don't need to specify a value with this switch.

The command: Set-AdServerSettings -ViewEntireForest $true to include all objects in the forest requires the ReadFromDomainController switch. Otherwise, the command might use a global catalog that contains outdated information. Also, you might need to run multiple iterations of the command with the ReadFromDomainController switch to get the information.

By default, the recipient scope is set to the domain that hosts your Exchange servers.

The ResultSize parameter specifies the maximum number of results to return. If you want to return all requests that match the query, use unlimited for the value of this parameter. The default value is 1000.

The SortBy parameter specifies the property to sort the results by. You can sort by only one property at a time. The results are sorted in ascending order.

If the default view doesn't include the property you're sorting by, you can append the command with | Format-Table -Auto Property1,Property2,...PropertyX. to create a new view that contains all of the properties that you want to see. Wildcards (*) in the property names are supported.

You can sort by the following properties:

• Name
• DisplayName
• ServerLegacyDN
