I am using the E1 Plan with Exchange Online from that plan and I have not deployed ADFS.
I am able to synchronize tasks manually by going to Sharepoint online and pressing the button to synchronize but I don't understand why this is not done automatically as I want to be able to setup my tasks and automatically see them on Outlook without having to "export" everytime I make changes.
Second issue is that after synchronizing I only see the sub-tasks but I have tasks + sub-tasks in hierarchy, how can I make it show properly in Outlook 2013 tasks, right now it is missing the hierarchy and only shows the sub-tasks and any tasks without sub-tasks which is very confusing since I can't see to which main task each item belongs to.
For example if I have:
Client 1:
- Upgrade e-mail to Office 365
- Do this do that
Client 2:
- Upgrade e-mail to Office 365
- Do this do that
In outlook I would see:
Upgrade e-mail to Office 365
Upgrade e-mail to Office 365
Do this do that
Do this do that
Which is basically useless as I won't be able to identify which client each item belongs to.
