I recently starting working in a new office that runs their Exchange email server internally, so in my Outlook settings it just lists a local domain as my Server. I would like to be able to receive my emails from my phone but the IT department won't provide me with a server domain that I can access outside of the office's network.
Is there a way that I can find out by myself the external domain? I've tried the obvious, mail.companyname.com, but no luck.
Thank you!
