Can I still download stock quotes without a Quicken subscription???

Unknown

I have Quicken 2016 and it will expired on April 30, 2019.  I do not use the online services of Quicken 2016 to download any data other than updating stock quotes at the end of the day.  Will the stock quote download feature I have enjoyed since 1991 be terminated at the discontinued date next year or can I continue stock quote downloading without upgrading to a subscription service?  Thanks in advance.

No you can't download quotes without upgrading, it is one of the "online services".

You might be able to import them manually if you can get them exported in CSV format from some place like Yahoo in the right format:
