  • You'll find this a lot easier to debug and provide a better experience for your users is you deploy split-brain DNS and use the same URLs internally and externally.

  • Hi SJ04,

    I suspect it could be caching causes. I recommend you test in anther laptop which is not joined domain, to check if it will connect with the internal URL first and then switch to External URL.

    And as Ed mentioned , it's recommended to deploy split-brain DNS and use the same URL both internal and external, the following article has provided more details about configuring exchange 2013 outlook anywhere, for your reference:

    Best regards,
