The following are directions for backing up Windows Live Mail 2011 on a computer running Windows 7. These directions might work on other versions of Windows and Windows Live Mail but the screen shots could look a little different depending on the versions installed on your computer. All of your Mail account settings, Contacts, and E-Mail Messages will be backed up.
To get started create some folders on your computer where the backups can be saved. Within the My Documents folder I created a folder called WLM Backups, and inside of that folder I created folders for Mail, Contacts, and Messages. I added a date-stamp to the Messages folder name so I can so more backups in the future and easily tell what date the backup was created on my hard drive.
To backup your Mail account settings click the Arrow in the top left of Windows Live Mail, select Export email, and then click on Account. Next highlight the mail account that you want to backup and click Export. Last, browse to the Mail folder that you created earlier, give the file a descriptive name, and click Save.
Repeat the above process for every email account that is configured on your computer.
To backup your email messages click the arrow in the top left, select Export Mail, and click Email Messages. Highlight the Windows Live Mail format and click Next.
Then browse to the dated Messages folder that you created earlier and click Next. Select All Folders and click Next. When the backup process is done click finish.
Last, it's time to backup the Contacts List saved in your Windows Live Mail.
Click Contacts in the lower left of your WLM and then at the top of WLM click Export and select Comma Separated Values (CSV)
Browse to the Contacts folder that you created earlier. Give the contacts file a descriptive name and click the Save button. Then click Next followed by Finish.
Congratulations, you are done backing up your Windows Live Mail!
Warning! Computers can crash. This is a great time to create a backup of your files so they can be stored in a safe place. If you have a flash/thumb drive you can copy your WLM Backups folder to it for safe keeping.
