Hallo Everyone

I've seen the Report for Exchange Mailboxes with OU, Send on Behalf, Full Rights and Send As Rights: https://www.adaxes.com/questions/10488/report-exchange-mailboxes-send-behalf-full-rights-send-rights

The Report above will search the Mailbox for the Users with Full Access permission, Send Behalf and Send As permission but, is it possible to go the other way around so that the User will be searched for the Mailboxes and list all Full Access permission, Send Behalf and Send As permission.

Example: image.png

User: Peter.Steinmann Identity: Which Mailboxes AccessRights: FullAccess

Kind regards,

Hello,

Do we understand correctly that you want to select a user for report generation and the report itself should contain Exchange mailboxes the user has Full Access permissions for?

Yes exactly

Hello,

Thank you for the confirmation. Please, find the script below. In the script:

  • $exchangeServer – Specifies the host name of the Exchange server to use.
  • $parameterName – Specifies the name of the AD object picker parameter used to select the user for search. The parameter name should be specified with the param- prefix.

For information on how to create reports, have a look at the following tutorial: https://www.adaxes.com/tutorials_ActiveDirectoryManagement_CreateReport.htm.

$exchangeServer = "exchangeServer.domain.com" # TODO: modify me
$parameterName = "param-MyParam" # TODO: modify me

try
{
    # Connect to Exchange server
    $session = New-PSSession -connectionURI "http://$exchangeServer/powershell" -ConfigurationName Microsoft.Exchange
    Import-PSSession -session $session -CommandName "Get-Mailbox", "Get-MailboxPermission" -AllowClobber

    $mailboxes = Get-mailbox -ResultSize Unlimited
    $guidsBytes = New-Object System.Collections.ArrayList
    $parameterValue = $Context.GetParameterValue($parameterName)
    foreach ($mailbox in $mailboxes)
    {
        $permissions = $mailbox | Get-MailboxPermission -User $parameterValue | Where{$_.AccessRights -like '*FullAccess*'}
        if ($NULL -eq $permissions)
        {
            continue
        }

        $guidsBytes.Add($mailbox.Guid.ToByteArray())
    }
}
finally
{
    # Close the remote session and release resources
    if ($session) { Remove-PSSession -Session $session}
}

# Add mailboxes to report
$searcher = $Context.CreateGuidBasedSearcher($guidsBytes)
$Context.Items.Add($searcher)

For your information, the report generation can take long time depending on the number of mailboxes you have. Unfortunately, there is no way to improve this without limiting the search scope as to obtain the desired it is required to first fetch all existing mailboxes and then check their permissions.

Thank you very much its working. Can i also add "Public Folder" Mailboxes to Search Criteria?

Hello,

Sorry for the confusion, but we are not sure what exactly you mean. Public folders do not have Full Access permissions. The following Microsoft article should be helpful: https://docs.microsoft.com/en-us/powershell/module/exchange/add-publicfolderclientpermission?view=exchange-ps. Please, specify what exactly you need to add to the report in terms of public folders.

Is there a way to do this with Exchange Online?

Is it Possible to add the comand to the Script so that Publicefolder will be search to like: -Name 'Access' -Value $_.AccessRights

Hello,

What exactly do you mean? We are not quite sure about the search criteria you specified. Could you, please, describe the desired report in all the possible details with live examples?
