Configuring preferences and options in Outlook.com
Hello yvonne
Hi, I'm Karl and will be happy to help you today.
You posted your quetion in the Outlook.com forum focused on accessing the account via webmail (using a browser) so not entirely clear why you are asking a question about your GMail account
If this is a question related to the Outlook desktop program (part of Office), the the folder should be in the <Deleted Items> folder and all you would need to do is drag it back from the <Deleted Items> folder to where you want it.
If the above doesn't cover what you are asking, please provide more details.
