Back story: I am in college and transitioned this exchange server from home late one evening. During the setup it cached my school's OWA site and now every once
in a while my users get a random login box asking for credentials to my schools OWA domain...very embarrassing.
I have looked through the certificates and did not find any reference to this domain, I have also looked through Exchange console and I did not see
anything referencing my schools login domain. Can someone give me a hint as to how to fix this? I have not seen any errors or information in the App event logs referring to this problem. I captured traffic using wireshark and when the login window appears,
it is actually communicating with my schools mail server IP. Could this be a certificate issue? I have looked everywhere I know to look in Exchange and I cannot find anything.
After doing a Test Email AutoConfiguration, it has my schools mail address for OOF URL and Availability URL under Protocol: Exchange HTTP - how do I change this?
