Parameters

-Anr

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.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Online

-Archive

The Archive switch filters the results by mailboxes that have an archive enabled (only mailboxes that have an archive mailbox are returned). You don't need to specify a value with this switch.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Online

-Async

This parameter is reserved for internal Microsoft use.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Online

-ExternalDirectoryObjectId

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.

Type:Guid
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False
Applies to:Exchange Online

-Filter

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 $null), use single quotation marks ' ' instead. Although this parameter is a string (not a system block), you can also use braces { }, but only if the filter doesn't contain variables.
  • Property is a filterable property. For more information about the filterable properties, see Get-EXOMailbox property sets and Filterable properties for the Filter parameter.
  • ComparisonOperator is an OPATH comparison operator (for example -eq for equals and -like for string comparison). For more information about comparison operators, see about_Comparison_Operators.
  • Value is the property value to search for. Enclose text values and variables in single quotation marks ('Value' or '$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 InactiveMailboxOnly switch specifies whether to return only inactive mailboxes in the results. You don't need to specify a value with this switch.

An inactive mailbox is a mailbox that's placed on Litigation Hold or In-Place Hold before it's soft-deleted. The contents of an inactive mailbox are preserved until the hold is removed.

To return both active mailboxes and inactive mailboxes in the results, don't use this switch. Instead, use the IncludeInactiveMailbox switch.

-MailboxPlan

The MailboxPlan parameter filters the results by mailbox plan. When you use this parameter, only mailboxes that are assigned the specified mailbox plan are returned in the results. You can use any value that uniquely identifies the mailbox plan. For example:

  • Distinguished name (DN)
