is it possible to add a task from Outlook to a task in todoist as a subtask?
There is currently no interaction between Outlook's own Tasks feature and Todoist. You can only use the "Add email as task" option through our Outlook plugin and if you do that within a project, you can of course use Ctrl+RightArrow to indent this task to make it a sub-task.
David, or others... is it possible do to the indention when not in a project, but in a time-based view like Today or Next 7 Days? or only on a project-level view?
Currently you can do the indent only inside your projects and not in the time-based views. Sorry about that!
