One good way to make sure that you are caught up on all of your email correspondence is by looking at the number of unread messages in a folder. If a message is marked as unread, then it probably means that you haven’t taken action on that message. But if you have just configured a new account, transferred messages from one folder to another, or changed a rule, then you might have a lot of messages that are marked as unread, but should not be that way. Fortunately you can easily mark an entire folder as read in Outlook 2013, meaning that you won’t need to individually click on each message.
Quickly Mark An Entire Folder as Read in Outlook 2013
Note that this does not delete any of these messages, it just removed the “unread” status from them. The messages are still in that folder, and will still show up in searches. They are just no longer bolder, and Outlook will treat them as being read. Additionally, this action can take some time if you have a high number of unread messages.
Step 1: Launch Outlook 2013.
Step 2: Locate the folder containing the messages that you want to mark as read.

Step 3: Right-click the folder, then select the Mark All as Read option.

Wait a few seconds (possibly longer if there a lot of unread messages) then the number in blue will disappear from next to the folder name, and there will no longer be any bolded messages in the folder. Note that new messages that come into the folder will still be marked as unread.
If you have a lot of important information on your computer, it is important to back it up. This is ideally accomplished to a different networked computer, server, or to an external drive. Click here to check pricing on an affordable 1 TB external hard drive.
