Whatz up with Sify on Airtel? Using Sify Email on Airtel always seems to be throwing up a false-positive error message like below when you login for the first instance: A mail session already exists in your browser. Please close the window and try again I have also reported this to Sify CustomerCare but they are still working on or at least in their endeavor to figure out what is causing this anomaly on accessing Sify Email specifically on Airtel broaband connections. All other networks work fine and seamlessly. It looks like a specific cookie issue but why does this manifest on a specific ISP connection is the big question that bugs everyone's mind.
