How do I go back to previous months on Microsoft Solitaire Collection to do the previous daily ...

I'm afraid you can't do it. The daily challenges are refreshed every month and only the current month is available. There are stats for each month keeping track on how you performed and also achievements tied to the
daily challenges, but the challenges themself are not kept at the end of each month.

When I play Microsoft solitaire collection for windows 10 the current months daily calendar page is available for play, however the previous months have disappeared and says challenges for this date are not yet available. They were there last week. This
happened last December and stayed about a month. It corrected itself. Anyone have a better solution other than waiting to see if it goes away?

How to play daily challenges other than current month.

1) Close all open applications

2) Change system date to end of month you wish to play (i.e. 11/30/2016)

3) Open Microsoft Solitaire Collection

4) Select Daily Challenges

5) Select Calendar tab and choose date you wish to play



Note: there are activities running in background on your system that will reset system date to current date. To continue to playing previous month repeat steps above.

There is not. You have the month to complete all the daily challenges but once that month is over, there isn't any way to go back and complete the previous month.
