I am retiring and want to have a countdown set up in my Outlook Calendar to that magic day. I learned that I can set up a .csv file in Excel with the necessary information and import it to the Calendar in Outlook. I used this strategy successfully at work with no issues. In attempting this at home I get a message indicating that this is "not supported by the service provider." This makes no sense, as my service provider is Comcast and they have NO connection to my Office 2016 suite other than as a transmitter and receiver of e-mails. Can someone please help me get this set up and working in my Outlook Calendar?

Thanks!

Greg
