How to undo a "scheduled folder"

I sign in as explained in the first link.

So i suposed i'm using Exchange.

I think so that imap and pop are disabled.

I found out how to fix it!

Go to online outlook.com then settings -> general -> mobile devices and then remove all mobile devices... after that youre bill able to delete any folder that is not system (inbox, sent, etc etc...) after that even if you install outlook android app schelduled mails will go to scheldued folder! :)

It's not working.

The folder I created is a subfolder of inbox folder.

I know the feeling, I have the same problem.  And it looks like there is no solution to this problem. I deleted the app and downloaded it again ... same thing.  But I found a solution. I got rid of the application.  Open my email with the android web (Chrome in my case) and it's a cell version that opens.  It is them back to normal.  I made a shortcut on my wall.  :)

So, on my phone, I accidentally made one of my folders "scheduled."  Now that folder has a clock next to it's name instead of a folder icon.  I don't know what I did to make that happen.  I don't know what a "scheduled" folder is.  I don't know what benefits I get from having a "scheduled" folder, but I don't want it to be that way.  In fact, I attempted to delete the folder on the outlook.com web app, but the "scheduled" folder continues to appear on my Android Outlook (formerly Acompli) app.  

Can anyone tell me how to undo what I've done?  And can anyone point me to any documentation which would explain what a "scheduled" folder is and why I might want one?

Let me try and explain my workaround. 

I too selected a folder by accident as a scheduled folder, in this case it was a folder collecting announcements from AWS. 

I noticed that "Announcements" folder disappeared from my desktop and OWA. Which means, Outlook mobile APP converted my "announcements" folder into a "scheduled" folder. 

I re-recreated "announcements" folder in my Outlook. (note, you need to re-check your rules now)

Went into my mobile Outlook app, selected all messages from "scheduled" folder and moved them back to the "announcements" folder. 

Now, there is a feature in Outlook mobile/web where you can "schedule" an email to come back to you, you can do this via a swipe setting, or from message menu. So basically now when you "schedule" emails, the automatically go into "scheduled" folder on your mobile Outlook, so you can take a look into that folder, and get a glimpse into all your emails that you have scheduled to come back to you. Sort of nice feature. 

But the initial process is not very well thought out, because it basically completely destroys your customer folder, and converts it into a "scheduled" folder, destroying all the rules you had set up for your custom folder. 

Hope this helps.
