Hi,
We are currently migrating a customer from Exchange 2013 to Exchange 2019. But before we actually start the migration I'm fixing some things that I find annoying.
Exchange 2013 works great, no complaints but when users go to the OWA or ECP page using a browser, you don't get the default blue/white logon page but instead you only get a username and password box. Looks very strange. Also when logging of from OWA it tells you to close the browser to end the session.
I believe this has to do with the config of the OWA and ECP virtual directories. I'm told I can switch these to Forms Based Authentication to fix this, however before I do, I need to know for sure if this in any way has an effect on Outlook connections. I have about 200 people that use Outlook without issue and I don't want any surprises...
