I am facing an issue now a days in outlook.com and working with new ideas but doesn't work upto now.
Do you face any problem with outlook.com changing color in hyper links to the background color or any other even i provide color in extrenal css with !impotant but still not working, and if we used tags of any ESP it shows the tags in the hyper link at that place.

Do you guys have any idea for it.
Either i am working on it, let me know if you have solution.

Thanks in advace
