Exchange URL Reconfiguration

Hi expert,

I configured all exchange server internal and external url as hostname.company.com which wasnt same as the standard url recommended by microsoft.

I suspect this caused the dns confusion and thats why external user are not able to login into the owa externally.

If i were to change the URL to standardized with microsoft guideline example: mail.company.com, what is the impact? or thing that i need to take note with?

You will have to make sure it is reachable if outlook using old names will be updated using autodisocver.
i.e. autodiscover.email.com assuming you are not planning to change email domain.
Make sure the name added to the certificate. Please check below article.

Internal URL would be server FQDN and external should be set as per your third party certificate SAN.

InternalUrl : https://server.FQDN/owa/
ExternalUrl : https://mail.domain.com/owa/

This is the default configuration.

How to is explained below article

hi everyone,

Based on all of your feedback, that's mean even if i did change the external URL in my EMC, it shouldn't have any huge impact does that correct?
