Microsoft Office Plugin - Proxy Issue

Microsoft Office Plugin - Proxy Issue

Hi..

I have an issue..
I want to use the Microsoft Office Plugin but my company uses Automatic Proxy Configuration Scripts to set up Proxies etc for Internet Explorer and Firefox.   The company does not tell us the Proxy info as it can change and the Automated Script handles this.

Why does the Zoho plugin require me to manually enter the proxy info when I want to login and authenticate?? 
Why cant it get this from Windows like every other application I use does?  This is not working smart guy's!!
All I should need to enter is my username and password and the rest should be handled automatically.
