There is no need to restart services, reset IIS, or anything. Visit the OWA logon page, and marvel at your handywork.Find right under that, insert a line with the following:.Open \Program Files\Microsoft\Exchange Server\ClientAccess\Owa\Auth\logon.aspx in notepad.Backup \Program Files\Microsoft\Exchange Server\ClientAccess\Owa\Auth\logon.aspx for safekeeping.On your Client Access Server, create a text file called disclaimer.inc in the \Program Files\Microsoft\Exchange Server\ClientAccess\Owa\Auth folder of your Exchange installation, and insert any additional code/text you want to include on your logon screen.The following set of instructions will add a custom disclaimer to Exchange but this can be adapted to add a custom logo into the page as well. I found it to be much easier than the original instructions for modification listed on the Microsoft site. Has something changed with Exchange 2010 UR3 when trying to customize OWA? I don't see anything documented about any change to OWA customization. I’ve tried restarting IIS on the CAS server and restarting the server but same results. I’ve even tried making my GIF file the same pixel size as the original LGNTOPL.GIF logo but still the same results. I’ve tried clearing my browser cache and even using multiple browsers from multiple PC’s but the same results. I’ve replaced the LGNTOPL.GIF file in each of the above directories but got the same results. “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\Current\themes\resources” “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.3.146.0\themes\resources” “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.3.123.3\themes\resources” I’ve searched and found a couple of other instances of LGNTOPL.GIF in the directories:


When I bring up OWA, I still get the original “Outlook Web App” logo. “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.3.158.1\themes\resources” I've created a new LGNTOPL.GIF file to replace the existing one in the folder: I have an Exchange 2010 UR3 deployment that I need to customize the OWA logon page for.
