I have a similar problem that is a real pain
I use the task list extensively ( take back your life - McGhee solutions methodology )
- If I have a task on day 1 that has a due date for day 1 and it sits on my task list into day 2 , it rightly shows up on day 2 as red ie as "overdue".
- If on day 2 I change the date ( day 1 date ) to "date none" it updates on my PC
<< NB if I change the date to a future date I do not have a problem - only happens when using "date none" on an overdue task >>
- At 9-9.15 am the next day ( day 3 ) the task shows up on my task list with the original late date ( day 1)
the only workaround I have found is :- instead of changing the date to " date none " instead I save it to a future date say 1st April 2020 leave the task for a day and then reopen it to change it to "date none"
A similar issue happens if I change the category of an overdue task - the next day it shows both categories
THE ISSUE HAS BEEN HAPPENING TO ANOTHER MEMBER OF MY TEAM THAT USES THE TASK LIST IN THE SAME WAY AND HAS BEEN HAPPENING FOR 2-3 MONTHS
THE PROBLEM HAPPENS ON THE ONLINE VERSION OF OUTLOOK TOO SO ITS SOMETHING TO DO WITH THE SERVER ????
Does anyone know how to fix this
