After updating our server (Small Business Server 2011 and PSB email and server security) yesterday, I am not able to open web UI. Internet Explorer 11 says that the page cannot be accessed. Yesterday, before updating, everything was working fine.
I updated the F-Secure to version (I guess it was 11) which I found via PSP Portal.
What could I try to solve this issue? I cannot check our spam mail in quarantine and check the settings.
