Verify the outgoing address is correct and make sure it wasn't typo or an improper autofill in the address OLK file.

message expired means it sat in the queue for delivery but the remote server didn't respond to a connection attempt in the allowed time (usually 3 days for retries)

if the address was invalid i would expect it to say invalid recipient from a remote server or DNS error if the domain was typed incorrectly

What exactly does the message tracking show?

Also try sending the message again and check the queues. Send the message a couple of times as the cmdlet has the messagecount value set higher then 1.

Get-Transportserver -ea silentlycontinue | Get-Queue -ea silentlycontinue | ?{$_.MessageCount -gt "1"} | Get-Message -IncludeRecipientInfo -ResultSize unlimited | Group-Object recipients | sort -Descending count | ft count,values
