Backing up your outlook inbox, local folders and sent folder to a .pst file on a regular basis can serve you well if your computer ever crashes. Making these backups a weekly or monthly routine is a good idea. To backup your Outlook 2010 email, please follow these instructions:
1. Bring up Outlook 2010
2. Click on the File Tab
3. Click on Open
4. Click on Import (You will see the blue and green arrows)
5. Choose Export to a file; then click next
6. Choose Outlook Data File .pst; then click next
7. Select the folder to export from; make sure you have “Include Subfolders” check at the bottom and click Next
8. Save the exported file to an area that is not on your local hard drive. Saving it to pangea or an portable external disk is a good idea. Name the file something that is descriptive such as “backup_sent_072212.pst”. It is a good idea to make the date part of the exported filename so it is easy to tell when you made your last backup.
9. Under “Options” read the three choices; I usually pick “Replace duplicates with items exported”.
