Email address no longer valid

An email address no longer valid message appears in Outlook as mailtip on certain internal recipients. The message reads as follows :

We won’t be able to deliver this message because the email address is no longer valid.

Additionally calendar delegates are not able to access the calendar of the person whose mail address displays the mailtip after it has been chosen from the GAL.

The Global Address List obtains the recipient’s address from the following fields which represent all the same attribute :

AD : Under user properties – General – E-mail field
AD : Under user attributes – Attribute Editor
Exchange Server – WindowsEmailAdress attribute
Query the WindowsEmailAddress attribute and the PrimarySMTPAddress :

Get-Mailbox -Identity someone.anyone@anydomain.com | select windowsemailaddress, primarysmtpaddress, emailaddresses

The value of the mentioned fields should be the same as the PrimarySMTPAddress or should at least contain an alias address from emailaddresses. Otherwise the email address no longer valid message will be displayed as mailtip.

If you have just a few affected recipients it is easier to just paste the PrimarySMTPAddress into the E-mail field under the general tab of user properties.

When this issue occurs with more recipients you may want to change it in bulk by setting the WindowsEmailAddress to the same value as the PrimarySMTPAddress.
In our case this problem occurred when a customer initially synchronized an OU via our Microsoft Identity Management server. Later he changed the PrimarySMTPAddress for all his mailboxes on our platform but left the initial synchronized E-mail address in the source AD.
So the initial address got synchronized again overwriting the changes.

Hope it helps when an email address no longer valid message starts to get on your user’s nerves.

Enjoy the summer

List Mailbox Attributes Powershell Script

List mailbox attributes to a customer is a recurring task.

The following script will provide a comprehensive list of the most relevant mailbox attributes and exported it to a .CSV file.

It will list the attributes expanded without the values being cut off by an ellipsis ( … ) as Exchange displays it by default.

#Define OrganizationalUnit
$customer = “OrgUnitName”

#Define certain customer domain within OrganizationalUnit / !! Comment out for results on all mailboxes within the OrganizationalUnit !!
$domain =”*DomainName*”

#CSV header , query mailbox attributes , define output
$output = “Alias;UserPrincipalName;DisplayName;PrimarySMTPAddress;FWSmptAddress;FWAddress;LegacyExchangeDN;EmailAddresses”

$org = get-mailbox -OrganizationalUnit $customer | Where-object {$_.PrimarySmtpAddress -like $domain}| Sort-Object Alias

$CustomerFile = “\\Fileshare\Folder\” + $Customer + “.csv”

$output > $CustomerFile

#Loop through mailboxes and provide results
foreach ( $mailbox in $org )
{
$FormatEnumerationLimit = -1

$Mailbox | Select-Object Alias,UserPrincipalName,DisplayName,PrimarySmtpAddress,ForwardingSmtpAddress,ForwardingAddress,LegacyExchangeDN,EmailAddresses

$output = $mailbox.Alias + “;” + $mailbox.UserPrincipalname + “;” + $mailbox.DisplayName + “;” + $mailbox.PrimarySmtpAddress + “;” + $mailbox.ForwardingSmtpAddress + “;” + $mailbox.ForwardingAddress + “;” + $mailbox.LegacyExchangeDN + “;” + $mailbox.EmailAddresses

$output >> $CustomerFile
}

Don’t forget to specify the folder path in $CustomerFile before you run the script!

I recommend leaving the EmailAddresses attribute at the end of the query. ( As it is right now )

This is because Excel breaks the .csv formatting when a result with many characters is displayed in a column somewhere in the middle.

Results will be displayed for these attributes in the following order :

Alias; UserPrincipalName; DisplayName; PrimarySMTPAddress; ForwardingSMTPAddress; ForwardingAddress; LegacyExchangeDN; EmailAddresses

You can find a description on how to expand all details in PowerShell here :

Expand powershell output to display all items

It could come in handy when you are in need of this kind of result.
