We have Win2003 Server with Exchange 2003 on a box. We always have OWA working. Suddenly our OWA is not working from outside. If we type https://owa.domain.com if gives out this error "Internet Explorer can not display the webpage". However, this is not happening internally. It works internally. it displaying the login information and users are ok to check their emails. internally i typed https://10.10.10.10
. I already restarted my IIS. and check my certificate. All looks on place. so any ideas? . We have not make any changes as i know.
I will appreciate your answers.
