Get-MailboxPlan

The AllMailboxPlanReleases switch specifies whether to include mailbox plans that were used in previous versions of the service in the results. You don't need to specify a value with this switch.

If you don't use this switch, the command returns only mailbox plans that are used in the current version of the service. This parameter has meaning only for organizations that were enrolled in previous versions of the service.

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

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

• Name
• Alias
• Display name
• Distinguished name (DN)
• GUID

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.

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 attributes:

• Alias
• DisplayName
• Name
