I have the following problems in sending and receiving calendar invite:

1. I am not able to use Windows Calendar to send out invitation, whenever
I send an invite, the recipient receive a blank e-mail message with no
calendar info to accept or decline.

2. Vice-versa, when I receive an invite, I am able to include in my
calendar, however, I can not find the accept/decline button on the e-mail to
respond.

Any solution to the above?
