Parameters
-ActiveSyncDebugLogging
The ActiveSyncDebugLogging switch shows the actual value of the ActiveSyncDebugLogging property for the mailbox. You don't need to specify a value with this switch.
If you don't use this switch, the value always appears as $false.
To see this value, you need to use a formatting cmdlet. For example, Get-CasMailbox laura@contoso.com -ActiveSyncDebugLogging | Format-List.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |

| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2016, Exchange Server 2019, Exchange Online |
-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
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online |
-Credential
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.
This parameter requires the creation and passing of a credential object. This credential object is created by using the Get-Credential cmdlet. For more information, see Get-Credential.
| Type: | PSCredential |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online |
-DomainController
This parameter is available only in on-premises Exchange.
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.
| Type: | Fqdn |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-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$null), use single quotation marks ' ' instead. Although this parameter is a string (not a system block), you can also use braces { }, but only if the filter doesn't contain variables. - Property is a filterable property. For more information about the filterable properties, see Filterable properties for the Filter parameter.
- ComparisonOperator is an OPATH comparison operator (for example
-eqfor equals and-likefor string comparison). For more information about comparison operators, see about_Comparison_Operators. - Value is the property value to search for. Enclose text values and variables in single quotation marks (
'Value'or'$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,$false, or$nullinstead).
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.

-IgnoreDefaultScope
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.

| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online |
-Monitoring
This parameter is available only in on-premises Exchange.
The Monitoring switch is required to return monitoring mailboxes in the results. You don't need to specify a value with this switch.
Monitoring mailboxes are associated with managed availability and the Exchange Health Manager service, and have a RecipientTypeDetails property value of MonitoringMailbox.

For example:
- Name
- Canonical name
- Distinguished name (DN)
- GUID
| Type: | OrganizationalUnitIdParameter |

-ReadFromDomainController
This parameter is available only in on-premises Exchange.
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.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
