Export Events with ICal

Hi,
I got an issue with the function “Export Events”.
I am using Outlook as Emailing software.
I got 2 cases:

1) Export Event with the view mode “Month”:
When I click on “Export Events”, only my events for the current selected month are exported. Then the button disappeared if I change month.
–> I would like to be able to export ALL the events in my Calender

2) Export Event with the view mode “List”:
When I click on “Export Events”, then ALL the events are correctly exported in my Outlook software. It works.

How can I do to export all the events in mode “Month” (like it work in mode “List”)?

Thank you very much for your help.
Best Regards
