Eddie,
<Inbox> in MLO is a very special place.
- it is the place for Inbox view
- it is the home for Rapid Task Entry tasks
- it is the home for Task By Email
- it is the home for the tasks which could not find parents due to different conflicts in move and/or sync
- it is the home for any other tasks MLO could not find where it to place
there are maybe other usage I could forget.
With such wide usage of the <Inbox> the MLO system should be sure that this place exists on each platform and it is the same place for all of them.
Since MLO is very flexible and each user may have completely different outline structure we decided that <Inbox> is the first folder with such name in the outline root. If it does not exist - it is created automatically just before using. We designed it a long time ago and it works this way for all platforms and cloud now.
The functionality of moving <Inbox> to other location and still receive TBE to it is not documented. It can be changed later during any bug fix.
Andrey.
P.S. I have just checked and even if you rename <Inbox> to other name after moving it from the root to other location it still receives the task by email. This is very strange even for me now...
