Your external DNS records will need to have the webmail A record updated to reflect the ISPs IP address you have.
Assuming you have a single static IP address AND you access OWA at https://webmail.company.com then you will need to either change/add yourself or get the ISP to change/add if they manage your Domain registration as weel.
You need and record for webmail A xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is your new IP address
