UNITED KINGDOM: County Field for Address
I'm from the UK and I use Microsoft Exchange in my Outlook For Mac.
UK addresses have 'County' i.e. Hertfordshire, Cornwall, Essex etc. This is the equivalent of a State in USA.
In Outlook for Windows, Microsoft Exchange, Apple Contacts, Old versions of Outlook for Mac, Google Contacts etc. this field exists as it's essential.
Outlook for Mac is the only place not to, so I presume it's an oversight?
