Move all exchange pages from default web site to a sub domain IIS

I have currently upgraded server and exchange to 2019. And now I would like to solve a problem which is follow me since years. The web access of my home page (Typo3) get always in conflict whit the exchange pages. Instead to get a Typo3 responce the exchange/owa login page will displayed.

My idea is to move all exchange pages to the sub domain mail. So instead of access the exchange pages with www.domain.com/.... I have to call mail.domain.com/...

I hope that would solve the conflict between exchange and the home page and also not change the IIS configuration after update exchange with a new CU.

Would this possible?

Solution 1:

You should not run other websites, or any other web content at all, on Exchange servers.

Exchange needs to have full control on IIS on the server where it's running, and it will overwrite any configuration change you manually make in IIS.

You can change the URLs for Exchange web services (including OWA), but you still really need to run everything that is not Exchange on a different web server.
