I'm trying to customize the favicon at the is location:
C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\owa\auth\15.0.1076\themes\resources
I created a file with our company logo to the same size and file name. However when I try to overwrite the current Microsoft favicon it stays the same. I then pasted it to the desktop and it looks correct but when replacing the favicon at the about location it reverts to the original. What is going on?
I did find other locations too so I'm not sure if I'm at the right location to the change the favicon. Please assist.
