I'm running into a strange issue. I upgraded my PS from r12.52 SP1 to r12.52 SP1 CR02.
My SPS is still on r12.52 SP1.
My office 365 Federation partnership was working without issue earlier.
Now when I access in IE, IE gives an error that says "IE has modified this page to prevent cross site scripting". This happens after authentication when the WSFED token is being submitted to login.microsoftonline.com
When I look at the developer tools, I see a lot of +++++ being added in the response headers And several %22. Could this be the reason why IE is flagging it? Other browsers let this go through fine.
