Google chat not working in Outlook.com

In the messaging pane in Outlook.com, at the bottom it gave me option "Add people to chat with" and mentioned "Google contacts" below it. I clicked on it, and approved the permission Outlook.com required. It sent me an email that the connection was successful. However, I'm not seeing my Google contacts in Outlook.com, instead it's still giving me the same option "Add people to chat with" and "Google contacts" is still in the list. At the bottom of the pane, I see "Connected to" and there are icons for Windows Live Messenger and Facebook only, not Google.

When I goto people.live.com, at top-right of the screen It says "Connected to" and shows icon of Google also, along with Windows Live Messenger and Facebook. But still in the messaging pane, there is no Google icon.

When I click on the gear icon in People, I can see "Google" in the "Filter all contacts" list, but when I uncheck others and keep only Google checked, there are no contacts appearing.

When I click on my name at top-right in the menu bar, there is no option of Google chat in "Available on > ", only Facebook chat On/Off is visible.

I have tried using different web browsers, and also removed the Google connection from Outlook.com, revoking the access from Google, and reestablished everything from a scratch, the scenario is still the same.

Please solve my issue asap!

Thank you!
