Hello everyone,

I believe our exchange server installed a service pack 3 update and after rebooting the server, we noticed that the Outlook web access login screen is not displaying correctly.  The page looks white with some black X's (I think that's where the pictures/background images used to be).  We tried to restart the ISS service with no luck.  I would appreciate any help you guys can provide.

Thanks,

Brian Kourdou

Hi

Any errors reported in the application log? I don't do service pack updates from windows update hence issues like this. Service pack installations should be planned. Which Exchange version are you referring to as there is no Exchange 2013 SP3?

Hello Brian,

I guess after installation of SP3,  core web files in virtual directory is not updated correctly, could you please try below

• Remove the IIS logs
• Re-install the .Net framwork once gain
• reboot the server
• check the status, if still  you have the issue
• Remove OWA virtual directory
• Re-create the OWA virtual directory
• Restart the server
