Delete multiple emails at once in Hotmail
HotmailUniversity
After reading your emails, one of the most common task you'll find yourself doing over and over again is to delete messages that you no longer need, or didn't want in the first place (whether they are newsletters you don't have time to read, annoying email forwards from colleagues, etc.) Depending on how you read your email messages in Windows Live Hotmail, deleting several emails at the same time may be the best solution; some people prefer to load the first email, and go through each email, and either file it or delete it once they are done. This methodical approach is the best defense against an overflowing inbox, but time constraints and reluctance towards such a painstaking effort may not make it feasible.
Deleting several emails at once in your Hotmail inbox / email folders
As discussed in the "Select multiple emails in Hotmail" tutorial, you can apply an action on multiple email messages at the same time. When it comes to email deletion, just check the checkbox of each email you want to send to the trash:
Once all messages are selected, simply hit the Del key on your keyboard (if you have not disabled keyboard shortcuts in Hotmail). You can also click on the "Move to" dropdown menu, and choose "Deleted", to move the selected messages to the deleted items folder (the trash), or drag-and-drop them above the Deleted folder:
Difference between deleting a single email message or multiple emails at once
From a practical standpoint, there is no difference whether you choose to delete email messages one-by-one, or to delete several emails in one go: it or they will be moved to the Hotmail.com special "Deleted" items email folder, from where they can be restored if you realize that you accidentally deleted an email you meant to keep.
Hotmail Tip: if you want to delete all spam emails inside your Junk mail folder, for example, you don't need to select each email message one after the other; instead, you can use the special "Empty Folder" command.
