Parameters

Parameters
Parameter	Description	Type	Required	Position	Accept Pipeline Input
Credential	Specifies Windows user credentials to connect to the Active Directory domain and the Exchange server.	Accepts the PSCredential object. To get this object, run the Get-Credential cmdlet.	False	Named	False
Mailbox	Specifies a mailbox. The cmdlet will check whether this mailbox is available.	Accepts the VEXMailbox[] object. To get this object, run the Get-VEXMailbox cmdlet.	True	Named	False
Office365Credential	Specifies a Microsoft 365 user account credentials to connect to the backup proxy server.	Accepts the PSCredential object. To get this object, run the Get-Credential cmdlet.	False	Named	False
Domain	Specifies a mailbox domain.	String	False	Named	False
Force	Defines that the cmdlet will ignore the certificate upon the connection. Default: False	SwitchParameter	False	Named	False
ApplicationId	Specifies a Microsoft Entra application ID. The cmdlet will use this application ID to set up a secure connection to a Microsoft organization. Note: This parameter works for mailboxes that are backed-up with Veeam Backup for Microsoft 365 only.	Guid	True	Named	False
ApplicationCertificatePath	To test mailbox resolution using multi-factor authentication. Specifies a path to the folder where the certificate is located. The cmdlet will import the certificate that is located in this path to set up an encrypted connection to a Microsoft organization and to test the mailbox resolution.	String	True	Named	False
ApplicationCertificatePassword	To test mailbox resolution using multi-factor authentication. Specifies the certificate password. The cmdlet will use this password to confirm the certificate that you want to import to a Microsoft Entra application. After that the cmdlet will set up an encrypted connection to a Microsoft organization and will test the mailbox resolution. This parameter is obligatory.	SecureString	False	Named	False

This cmdlet supports Microsoft PowerShell common parameters. For more information on common parameters, see the About Common Parameters section of Microsoft Docs.

Examples

Example 1. Testing Mailbox Resolution [For Veeam Backup & Replication]

This example shows how to test the availability of Exchange mailboxes.

$credentials = Get-Credential

$session = Get-VBRExchangeItemRestoreSession

$database = Get-VEXDatabase -Session $session -Name "DB_0754907780.edb"

$mailbox = Get-VEXMailbox -Database $database

Test-VEXMailboxResolution -Mailbox $mailboxes -Domain test.local -Credential $credentials

Perform the following steps:

Run the Get-Credential cmdlet. Type Windows credentials to connect to the Active Directory domain and the Exchange server. Save the result to the $credentials variable.
Run the Get-VBRExchangeItemRestoreSession cmdlet. Save the result to the $session variable.
Run the Get-VEXDatabase cmdlet. Set the $session variable as the Session parameter value. Specify the Name parameter value. Save the result to the $database variable.
Run the Get-VEXMailbox cmdlet. Set the $database variable as the Database parameter value. Save the result to the $mailbox variable.
Run the Test-VEXMailboxResolution cmdlet. Specify the following settings:

Set the $mailbox variable as the Mailbox parameter value.
Specify the Domain parameter value.
Set the $credentials variable as the Credential parameter value.

Example 2. Testing Mailboxes Resolution [For Veeam Backup for Microsoft 365]

This example shows how to test the availability of Exchange mailboxes from the support3backup.onmicrosoft.com backed-up Exchange organization.

$credentials = Get-Credential

$session = Get-VBOExchangeItemRestoreSession

$database = Get-VEXDatabase -Session $session -Name "support3backup*"

$mailboxes = Get-VEXMailbox -Database $database

Test-VEXMailboxResolution -Mailbox $mailboxes -Domain test.local -Credential $credentials

Perform the following steps:

Run the Get-Credential cmdlet to create a credential object. Type Windows credentials to connect to the Active Directory domain and the Exchange server. Save the result to the $credentials variable.
Run the Get-VBOExchangeItemRestoreSession cmdlet. Save the result to the $session variable.
Run the Get-VEXDatabase cmdlet. Set the $session variable as the Session parameter value. Specify the Name parameter value. Use the * wildcard character to substitute the timestamp. Save the result to the $database variable.
