Hello,

I think in the own email service there is a folder that all your deleted emails went, in hotmail is electronic garbage and deleted items

or you will need emails manager, as outlook!

Do you use an online webmail site like Yahoo or Gmail? These sites usually make a distinction between moving an item to the Trash folder and permanent deleting. Some also have archiving features, and/or let you create your own folders to stores messages for future reference. But if you have any questions about it, I would check their help pages to make sure because each one works a little differently.

P.S. If you want to save emails outside of your email service, you can print them to PDF. This generally is safer than using Firefox's feature to save them as web pages, because those may not always be complete, or may contain security features that make them hard to view offline (when you're logged out). If you need an add-on to capture pages to PDF, try this one: https://addons.mozilla.org/en-US/fire.../print-pages-to-pdf/. To access it, right-click on the page you want to save.
