Get-Mailbox
This cmdlet is available in on-premises Exchange and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.
Use the Get-Mailbox cmdlet to view mailbox objects and attributes, populate property pages, or supply mailbox information to other tasks.
Note: In Exchange Online PowerShell, we recommend that you use the Get-EXOMailbox cmdlet instead of this cmdlet. For more information, see Connect to Exchange Online PowerShell.
For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

When you use the Get-Mailbox cmdlet in on-premises Exchange environments to view the quota settings for a mailbox, you first need to check the value of the UseDatabaseQuotaDefaults property. The value True means per-mailbox quota settings are ignored, and you need to use the Get-MailboxDatabase cmdlet to see the actual values. If the UseDatabaseQuotaDefaults property is False, the per-mailbox quota settings are used, so what you see with the Get-Mailbox cmdlet are the actual quota values for the mailbox.
You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
Get-Mailbox -ResultSize unlimited
This example returns a summary list of all the mailboxes in your organization.
Get-Mailbox -OrganizationalUnit Users
This example returns a list of all the mailboxes in your organization in the Users OU.
Get-Mailbox -Anr Chr
This example returns all the mailboxes that resolve from the ambiguous name resolution search on the string "Chr". This example returns mailboxes for users such as Chris Ashton, Christian Hess, and Christa Geller.
Get-Mailbox -Archive -Database MBXDB01
This example returns a summary list of all archive mailboxes in the database named MBXDB01.
Get-Mailbox -Identity ed@contoso.com -RemoteArchive
This example returns information about the remote archive mailbox for the user ed@contoso.com.
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

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$null
), use single quotation marks ' ' instead. Although this parameter is a string (not a system block), you can also use braces { }, but only if the filter doesn't contain variables. - Property is a filterable property. For more information about the filterable properties, see Filterable properties for the Filter parameter.
- ComparisonOperator is an OPATH comparison operator (for example
-eq
for equals and-like
for string comparison). For more information about comparison operators, see about_Comparison_Operators. - Value is the property value to search for. Enclose text values and variables in single quotation marks (
'Value'
or'$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'$User'
, use'$($User -Replace "'","''")'
. Don't enclose integers or system values in quotation marks (for example, use500
,$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.
