[<CommonParameters>] Description
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.
Examples
Example 1
Test-SystemHealthThis example gathers data about your Exchange system.
Example 2
$SysHealth = Test-SystemHealth -OutData
[System.IO.File]::WriteAllBytes('D:\temp\SystemHealthOutData.xml', $SysHealth.FileData)This example saves the output data as a byte stream to the variable named $SysHealth. The content is then written to the SystemHealthOutData.xml file in the D:\temp folder.
Parameters
-ADCredentials
The ADCredentials parameter specifies the username and password that's used to access Active Directory. 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.
| Type: | PSCredential |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010 |
-Analyze
The Analyze switch enables analysis on the data gathered. 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 |

-ConfigurationData
This parameter is reserved for internal Microsoft use.
| Type: | Byte[] |

-ConfigurationFileLocation
This parameter is reserved for internal Microsoft use.
| Type: | LongPath |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |

-Confirm
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax:
-Confirm:$false. - Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.
