Desktask was working great with Outlook 2010 but after I installed Outlook 2019 Desktask can't seem to find any appointments. The appointments show in Outlook calendar but in Desktask just a message "No appointments found"

I found a solution. Open Outlook and select the file tab open account setting and click account settings under the email tab I deleted the hotmail account then open the data files tab and select the outlook item that shows a .pst file ending and make it the default calendar.

HI Warren,

Glad you found a solution.
DestkTask only supports default calendars from Outlook (PST)

Thanks for taking time to post your solution,
