Script Repository

All mailbox delegates

October 18, 2023 Views: 2336

The script creates a CSV-formatted report on delegates of on-premises Exchange mailboxes in all domains managed by Adaxes.

To schedule a report, create a scheduled task configured for the Domain object type that runs the script and assign it over any of your AD domains. To add the script to a scheduled task, use the Run a program or PowerShell script action.


  • $csvFilePath - Specifies a full path to the CSV file containing the report.

$csvFilePath = "\\Server\Share\MailboxDelegates.csv" # TODO: modify me

function SearchObjects($criteria, $properties)
    $searcher = $Context.BindToObject("Adaxes://rootDSE")
    $searcher.Criteria = $criteria
    $searcher.SearchScope = "ADS_SCOPE_SUBTREE"
    $searcher.PageSize = 500
    $searcher.ReferralChasing = "ADS_CHASE_REFERRALS_NEVER"
    $searcher.VirtualRoot = $True
        $searchResultIterator = $searcher.ExecuteSearch()
        $searchResults = $searchResultIterator.FetchAll()
        return ,$searchResults
        # Release resources
        if ($searchResultIterator){ $searchResultIterator.Dispose() }

# Search mailbox
$criteria = New-AdmCriteria "user" -Expression {publicDelegates -empty $False}
$searchResults = SearchObjects $criteria @("publicDelegates")

# Build report
$report = New-Object System.Collections.ArrayList
foreach ($searchResult in $searchResults)
    # Get mailbox name.
    $mailboxDisplayName = $Context.GetDisplayNameFromAdsPath($searchResult.AdsPath)

    $publicDelegates = $searchResult.Properties["publicDelegates"].Values
    for ($i = 0; $i -lt $publicDelegates.Count; $i++)
        # Get object name.
        $displayName = $Context.GetDisplayNameFromAdsPath("Adaxes://$($publicDelegates[$i])")
        # Build record

        # Add record to the report

# Export to CSV file

Will this work with mailboxes in Exchange Online?

Hello Ray,

No, the script will not work for pure Exchange Online mailboxes. Unfortunately, there is no easy way to do that.
