Get-EXOCasMailbox

This parameter is reserved for internal Microsoft use.

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

You can't use this parameter with the ExternalDirectoryObjectId, Identity, PrimarySmtpAddress, or UserPrincipalName parameters.

The ExternalDirectoryObjectId parameter identifies the mailbox that you want to view by the ObjectId in Microsoft Entra ID.

You can't use this parameter with the Anr, Identity, PrimarySmtpAddress, or UserPrincipalName parameters.

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 $null), use single quotation marks ' ' instead. Although this parameter is a string (not a system block), you can also use braces { }, but only if the filter doesn't contain variables.
• Property is a filterable property. For more information about the filterable properties, see Get-EXOCasMailbox property sets and Filterable properties for the Filter parameter.
• ComparisonOperator is an OPATH comparison operator (for example -eq for equals and -like for string comparison). For more information about comparison operators, see about_Comparison_Operators.
• Value is the property value to search for. Enclose text values and variables in single quotation marks ('Value' or '$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 mailbox you want to view. For the best performance, we recommend using the following values:

• User ID or user principal name (UPN)
• GUID

Otherwise, you can use any other value that uniquely identifies the mailbox. For example:

• Name
• Alias
• Distinguished name (DN)
• Domain\Username
• Email address
• LegacyExchangeDN
• SamAccountName

You can't use this parameter with the Anr, ExternalDirectoryObjectId, PrimarySmtpAddress, or UserPrincipalName parameters.

This parameter is reserved for internal Microsoft use.

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 visible using 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 PrimarySmtpAddress identifies the mailbox that you want to view by primary SMTP email address (for example, [email protected]).

You can't use this parameter with the Anr, ExternalDirectoryObjectId, Identity, or UserPrincipalName parameters.

The Properties parameter specifies the properties that are returned in the output of this cmdlet. You can specify multiple values separated by commas.

For more information about the available properties, see Get-EXOCasMailbox property sets.

The PropertySets parameter specifies a logical grouping of properties that are returned in the output of this cmdlet. Valid values are:

• Minimum (this is the default value)
• ActiveSync
• Ews
• Imap
• Mapi
• Pop
• ProtocolSettings
• All

You can specify multiple values separated by commas.

For more information about the properties that are included in each property set, see Get-EXOCasMailbox property sets.

The ProtocolSettings switch returns the server names, TCP ports and encryption methods for the following settings:

• ExternalImapSettings
• InternalImapSettings
• ExternalPopSettings
• InternalPopSettings
• ExternalSmtpSettings
• InternalSmtpSettings

You don't need to specify a value with this switch.

To see these values, you need to use a formatting cmdlet. For example, Get-CasMailbox [email protected] -ProtocolSettings | Format-List.

This parameter is reserved for internal Microsoft use.

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.

This parameter is reserved for internal Microsoft use.

The UserPrincipalName parameter identifies the mailbox that you want to view by UPN (for example, [email protected]).

You can't use this parameter with the Anr, ExternalDirectoryObjectId, Identity or PrimarySmtpAddress parameters.
