How to Import Information in Outlook
If you have Outlook data saved in a file on your computer, it is simple to import it back into Outlook. For example, if you want to import contacts from another program, importing the file is the easiest way to do it.
The Import and Export Wizard appears.
You can import an Outlook Data File created in Outlook or a Comma Separated Values file created in another program.
You can replace duplicate items with the item being imported, allow duplicate items to be created, or skip importing items that would create duplicates.
You can import an entire archive file, or you can choose only a single folder from it.
If you don’t want to import the entire archive or folder, click the Filter button to add a filter so that only items that meet the filter criteria are imported.
The file’s contents are added to your inbox.
