When you get "unresolved recipients" it means one oor more of the email addresses is mal-formed. It has got to the point of knowing if the email addresses are valid and 'live'. It's just that there's something in the list that's wrong.
; johnsmith_abc.com; firstname.lastname@example.org
This will show as an unresolved recipient.
Outlook, as an application, knows that there's something wrong and warns you.
OWA doesn't have this checking ability so it just fires it off and only errors if something can't be delivered.
Also many of these email addresses are company email addresses so if they leave their company this may just happen again in the future.
This won't cause the unresolved error. In this instance the email will be sent but those address not in use will return undeliverable.
The only way to resolve the issue is to look at the address list.
Copy and paste it to a text editor and replace all the semi-colons with carriage returns so you can see each address on a line on it's own. Shold be easy to spot the typo/grammer issue. Remember.... so long as the address is formed something@something it won't give you the unresolved error
