I feel like the archive one is easy to fix. This is MS Outlook's and MacOS's archive button - https://i.imgur.com/Csjpgth.png https://i.imgur.com/Csjpgth.png - if you can't see that, it's a filing cardboard box with it's oversized lid fit on top. I use MS Outlook web UI and exchange on MacOS with an Apple mail client. Also then by 'fixing' the archive one to this better one, you sort of also fix the 'Move to Inbox' icon because it's not so similar. The 'Move to Inbox' isn't to bad if it's by itself, what makes it bad as the author says is it's context. I'm not sure what a better 'Move to Inbox' icon would be, I'm not a skilled icon designer.
