If your using a domain such as owa.mydomain.com you would need a forward lookup zone, not a reverse lookup on your DNS server.

the iphones are using wifi in the office during this time?

to be clear, you created an A record in DNS.  Is that A record the same name as the external server name?

If your internal AD DNS is domain.local and your external domain name is mydomain.com
external server name is:  owa.mydomain.com

then you would need to make a new DNS forward lookup zone called mydomain.com and an A record called owa (owa.mydomain.com) with the LAN IP for your server.

then that should 'trick' the iphone while inside the office.

If you create the mydomain.com zone on your internal DNS then you will probably need to also create A records for any outside hosts for your domain such as www, ftp, etc with the Internet IP addresses.   so that users on the LAN can access the external hosts still

I have created a new forward zone mydomain.co.uk with an A record inside called mail as the outside address is https://mail.mydomain.co.uk but still no joy

you're on wifi or not?  can you check your tcp/ip DNS setting in the iPhone and make sure they are your LAN DNS servers.

The A Record name can be left blank.  Windows DNS server will then show '(same as parent folder)' as the name.

Assuming you are using the Windows Server DNS it should look something like the below:
 DNS Server
The names servers should be you DNS server(s).  We have two so both are listed - if you only have one then only one will be listed.

In order to check if this has worked, on a computer that is on the local domain (or the iPhone if you have an app), run NSLookup, and enter your domain name for OWA - e.g. mail.yourdomain.com (obviously changing the yourdomain.com to your actual domain name).  If should return the internal IP address of you OWA server if the DNS has been set up correctly.
Yes it does, its finally working, thank you for your help
