Hi team,
anyone know of a way that a project which was deleted is recoverable? Have tried looking at browser history etc but nothing going? Is the project forever lost? We even tried logging in and out of the same account twice which restored some of our other deleted projects but not the one we were looking for. 
I’m pretty sure that once you delete your project it’s gone forever. Happened to me once and one time (when I was pretty new to MakeCode), I accidentally pressed a button that deleted all my projects.
assuming you pressed the “delete” button, I don’t think it’s recoverable
Welcome @lancelot360, unless you have the project link, or have it saved or downloaded, you can’t recover deleted projects.
Beyond what others said, if you just mean more like missing (that is you didn’t press delete), one thing to do first would be to check the other log in options – e.g. if you logged in with gmail check if logging in through microsoft (even with the gmail) works. A large number of folks have had that sort of situation, where they’ve logged in with the ‘wrong’ account by going through a different authentication route
ALL OF!!??!
that must have been terrible
Thank you all. I did think that it was unlikely. I’m going to cry on the couch now. 
Lesson learned…
