Modify OWA 2013 page title

Hi All.

I'm currently in the processes of branding up OWA 2013. I've pretty much got everything covered, but I've run into a bit of a roadblock with the page title.

To clarify. I've changed the title for the login page, it's changing the title for a logged in session that I'm struggling with. Currently the title displays as "User Display Name - Outlook Web App". I would Ideally like to leave the user's display name and just change "Outlook Web App".

I've looked at pretty much everything under "C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa" and it doesn't look like it's as simple as just changing an ASPX file. I noticed the file "Microsoft.Exchange.Clients.Strings.dll" in the folder "C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa\Bin". I opened this up with a decompiler (.NET reflector) and can see that there's a Resources table called "Microsoft.Exchange.Clients.Strings" which contains, amongst many other strings, a string called OwaTitle, which is set to "Outlook Web App".

It seems to me fairly likely that I've located where the string originates however I'm not a dev and I wouldn't even know where to begin modifying this and recompiling. (In fact, as it happens, Visual Studio won't even open the resource file that is created from decompiling the dll). I've also tried to find and edit the string using a hex editor but it must be encoded in some way as I was unable to find the string in the file.

I'm pretty much resigned to the high likelihood that this isn't possible, but I thought it was worth posting here in case anyone else has had this requirement and worked out a solution.

Many Thanks.
