Hello Support Team

We are looking to change our email address format to first.last@company.com. We have some newer users using the new format but we never backfilled the existing users. How would we systematically add a secondary email address (NOT set to primary) to each account and deal with the possibility of duplicates?

Hello,

Could you specify whether it has to be done for on-premise mailboxes, Office 365 mailboxes or both?

0

This would be for on premise only at this time.

Hello,

Do we understand correctly that you actually have a hybrid environment, but the update should be done only for on-premise mailboxes?

0

We are prepping for an hybrid environment. Today is onprem exchange only.

Hello,

Thank you for clarifying, you need to create a Scheduled Task like the following:

For information on how to create Scheduled Tasks, have a look at the following tutorial: https://www.adaxes.com/tutorials_Automa ... gement.htm.

Thank you for the quick response. We will test.

One question will this just fail if a email address is already named the same? We would want it to do what we currently do and randomize a two digit number after the lastname.

Hello,

If the user has the primary or secondary address email set to firstname.lastname@company.com, the task will not affect the user at all. If you need a different behavior, specify all the possible details and we will provide detailed instructions.

We need the script to check and verify the desired email address of firstname.lastname@company.com is available and if not randomize 2 digits to the end of the lastname.

Hello,

Thank you for clarifying. You need to use the below script and a Scheduled Task configured for User Object type. The task needs to be executed just once.

$addressToAdd = "%firstname%.%lastname%@company.com" # TODO: modify me

function IsAddressUnique($value)
{
    $searcher = $Context.BindToObject("Adaxes://rootDSE")
    $searcher.SearchFilter = "(&(sAMAccountType=805306368)(proxyAddresses=smtp:$value))"
    $searcher.SearchScope = "ADS_SCOPE_SUBTREE"
    $searcher.PageSize = 500
    $searcher.ReferralChasing = "ADS_CHASE_REFERRALS_NEVER"
    $searcher.SetPropertiesToLoad($properties)
    $searcher.SizeLimit = 1
    $searcher.VirtualRoot = $True

    try
    {
        $searchResultIterator = $searcher.ExecuteSearch()
        $searchResults = $searchResultIterator.FetchAll()

        return $searchResults.Length -eq 0
    }
    finally
    {
        # Release resources
        if ($searchResultIterator){ $searchResultIterator.Dispose() }
    }
}

function AddNewEmailAddress($addressToAdd, $mailboxParams)
{
    $emailAddresses = $mailboxParams.EmailAddresses

    # Create a new e-mail address
    $emailAddress = $emailAddresses.CreateAddress("ADM_EXCHANGE_ADDRTYPE_SMTP", $null)
    $emailAddress.Address = $addressToAdd
    $emailAddress.IsPrimary = $False

    # Add the new e-mail address to the existing list
    $emailAddresses.Add("ADS_PROPERTY_APPEND", $emailAddress)
    $emailAddresses.OverrideOldValues = $False
    $mailboxParams.EmailAddresses = $emailAddresses

    $Context.TargetObject.SetMailParameters($mailboxParams, "ADM_SET_EXCHANGE_PARAMS_FLAGS_NONE")
}

if ($Context.TargetObject.RecipientType -ne "ADM_EXCHANGERECIPIENTTYPE_MAILBOXENABLED")
{
    return
}

$mailboxParams = $Context.TargetObject.GetMailParameters()
foreach ($emailAddress in $mailboxParams.EmailAddresses.GetAddressesByPrefix("smtp"))
{
    if ($emailAddress.Address -eq $addressToAdd)
    {
        return
    }
}

# Add new address
if (IsAddressUnique $addressToAdd)
{
    AddNewEmailAddress $addressToAdd $mailboxParams
    return
}

$addressParts = $addressToAdd.Split("@")
$addressFirstPart = $addressParts[0]
$addressDomainPart = $addressParts[1]
for ($i = 1; $i -le 100; $i++)
{
    $uniqueEmailAddress = $addressFirstPart + $i.ToString("00") + "@$addressDomainPart"
    if (IsAddressUnique $uniqueEmailAddress)
    {
        AddNewEmailAddress $uniqueEmailAddress $mailboxParams
        return
    }
}
