How To Recover and Move Archived Emails Back To GMail Inbox
Archived Messages are not labelled while messages in the inbox have the "inbox" label. So, to move an archived message back to the inbox, follow the steps below:
1. Find the message (as explained earlier).
2. Open the message (or select the checkbox next to it).
3. Click the Move to Inbox button in the toolbar.
I hope this helps.
